Adds a Moon dashboard widget, next to the existing Sun one.
It shows the moon as a real photo with the shadow of the current phase drawn over it, along with the phase name and illumination. An optional detail panel lists the distance, the age of the moon, whether it is waxing or waning, its trajectory, the constellation it stands in, moonrise and moonset, and the countdowns to the next full moon, new moon, perigee, apogee, node and lunar eclipse.
Everything is computed locally from suncalc, which was already a dependency: no external API, no API key, no network call at runtime.
Two options in the widget settings:
Display details (on by default) — turn off to keep only the moon, its phase name and its illumination.
Compute the values at midnight (off by default) — computes illumination, distance, age and the upcoming events at local midnight, the way lunar calendars publish them, so the widget can be compared with them line by line. Moonrise and moonset belong to the day and are not affected.
Server side: new GET /api/v1/house/:house_selector/moon route, backed by gladys.house.getMoonState(), which uses the house coordinates and the instance timezone.
Moon image: moon.png is a crop of the lunar disk from NASA's Scientific Visualization Studio (Moon Phase and Libration, 2025), public domain, resized to 256×256 and masked to a circle (21 KB). Credit and processing details are in front/src/components/boxs/moon/CREDITS.md.
Accuracy: the simplified series used by suncalc gives the right dates but times that can be off by a few hours, which is not visible on a "in 5 days" countdown. The constellation uses the sidereal zodiac (with the Lahiri ayanamsa), like lunar calendars do, not the tropical one. The eclipse search is reliable on the date, less so on the exact type and time.
Checklist
Tests pass: cd server && npm run coverage (Codecov requires 100% coverage on changed lines) and Cypress (npm run cypress:run) if the UI changed
Linter and prettier pass on both front and server (npm run eslint, npm run prettier)
No undocumented breaking change

Summary
Existing feature routes server/api/routes.js
Adds authenticated device-state export and administrator-only host control routes.
The Moon widget may show moonrise and moonset in the viewer’s browser timezone even though they are computed for the instance timezone, so users in different timezones may see misleading times. This is a bounded display-correctness issue; the PR is mergeable with explicit owner awareness or follow-up.

Stale comment
Thanks for this PR — it follows the sun widget pattern well (house coordinates, instance timezone, suncalc, no network, request-id refresh, tests for polar days / DST / Tokyo).
Not risk:high. Additive dashboard box + GET /api/v1/house/:house_selector/moon. No device categories, no actuation, no new network surface.
needs:human-review + Pierre-Gilles: this is less a small companion to the sun card and more a lunar calendar (sidereal zodiac, nodes, perigee/apogee, eclipse type). That is a product call on Gladys’s “beautiful by default / a few clicks” bar, and on whether ~500 lines of custom ephemeris belong in core next to suncalc.
Blocking
The next-node North/South label is wrong about half the time.next_node_ascending is copied from the current latitude trend, but the next ecliptic crossing is northbound only while the moon is still south of the ecliptic. After the ascending node, latitude is still rising for ~7 days — the next node is then the descending one. The test expect(next_node_ascending).to.equal(ascending) currently locks that in. See the inline comment.
Product / philosophy (for Pierre-Gilles)
Scope vs the sun widget. Sun is rise/set + a curve. Moon adds a 12-row panel by default: distance, age, waxing, trajectory, “constellation”, rise/set, full/new, perigee/apogee, node, eclipse. Details can be hidden, but the default is a lot of card for a wall dashboard.
“Constellation” is the 12 equal sidereal signs (Lahiri), not IAU constellations (no Ophiuchus, equal 30° slices). Fine for a lunar almanac; easy to read as astrology. Worth an explicit yes/no.
Eclipse type is disclosed as approximate (penumbral vs partialOrTotal). Showing a type you already distrust may be worse than date-only.
Moon drawing is north-up / northern-hemisphere calendar style (waxing lit on the right). Documented; southern-hemisphere users will not see the sky as they see it. OK if intentional.
Non-blocking
Demo mode has GET /api/v1/house/main-house/sun but no moon mock. The demo dashboard does not include a moon box, so this only bites if someone adds one in demo.
Moonrise/moonset HH:mm is formatted in the browser timezone, not the instance timezone. Same as the sun widget — not unique to this PR. CodeRabbit already flagged it.
dayjs(date).diff(..., 'day') is whole 24h periods, so an event 20 hours away renders as “today”. Acceptable for “in N days”, slightly coarse.
toLocaleString() on the distance uses the browser locale, not Gladys’s language.
No Cypress; the sun widget did not add any either.
The living dashboard spec does not catalog every box type (sun is absent too); I would not block on it.
What looks good
Generic DASHBOARD_BOX_TYPE.MOON only — no brand-tied device categories.
Joi fields display_details / compute_at_midnight, wired like the sun route (auth, 400 without coordinates, 404 missing house).
Timezone handling matches the sun lessons (local noon for suncalc truncation, local-day moonrise/set, midnight option in the instance TZ).
NASA SVS crop + CREDITS.md is the right way to ship the image.
i18n keys look aligned across en/fr/de; refresh/unmount guard copies the sun widget.
I would not merge until the node label is fixed (or the North/South suffix is dropped). The rest is a maintainer call on how much lunar almanac Gladys wants in a core dashboard card.

Stale comment
Thanks for the follow-up. The previous blocking issue is fixed.
next_node_ascending is now derived from the sign of ecliptic latitude (eclipticLatitude < 0), with regression tests for both mixed cases (north of the ecliptic and still climbing → next node descending; south and still falling → next node ascending). The old assertion that locked the bug in (next_node_ascending === ascending) is gone.
Not risk:high. Additive dashboard box + authenticated GET /api/v1/house/:house_selector/moon. No device categories, no actuation, no new network surface.
Keep needs:human-review + Pierre-Gilles: this is still more a lunar almanac than a small companion to the sun card (sidereal/Lahiri zodiac labeled as “constellation”, nodes, perigee/apogee, eclipse type). That product call on Gladys’s “beautiful by default / a few clicks” bar, and on whether ~500 lines of custom ephemeris belong in core next to suncalc, has not changed. I would not block merge on it from a code standpoint.
Remaining non-blocking notes
Demo mode still mocks GET /api/v1/house/main-house/sun but not moon. The demo dashboard does not include a moon box, so this only matters if someone adds one there.
Moonrise/moonset HH:mm is still formatted in the browser timezone. Same convention as the sun widget; changing only this card would make the two disagree.
dayjs().diff(..., 'day') is whole 24h periods, so an event 20 hours away renders as “today”. Fine for “in N days”.
toLocaleString() on the distance uses the browser locale, not Gladys’s language.
Eclipse type remains approximate (penumbral vs partialOrTotal), as disclosed in the PR body.
What looks good
Generic DASHBOARD_BOX_TYPE.MOON only — no brand-tied device features.
Joi display_details / compute_at_midnight, same auth/400/404 pattern as the sun route.
Timezone handling matches the sun lessons (local noon for suncalc truncation, local-day moonrise/set, midnight option in the instance TZ).
NASA SVS crop + CREDITS.md; i18n keys aligned across en/fr/de; refresh/unmount guard copied from the sun widget.
Perigee/apogee test now also checks that distance at perigee is smaller than at apogee.
CI is green (front/server tests, Cypress, Docker, codecov patch).
Code-wise this is good to merge. Please keep Pierre-Gilles on the product/scope call before landing if that still needs a maintainer yes.
Thanks @William-De71, this is really nice work 🌖 — local computation with suncalc (no external API, very much in line with the privacy-first philosophy), the request-race handling, the non-flashing loader and the "compute at midnight" option are all well thought out, and the terminator rendering is elegant.
One piece of feedback on the design of the details column: it currently feels a bit raw — twelve identical rows with no grouping or hierarchy. Everything has the same visual weight (the Earth-Moon distance reads as important as moonrise), the label-left / value-right pattern creates a wide empty gutter on large cards, and a few rows are redundant ("Phase: Waxing" repeats what "Waxing Gibbous" already says, "(North)" and "(penumbral)" in parentheses read like log output).
Here is a proposal that keeps exactly the same data, no new dependency, existing Tabler classes only — just reorganized in three levels:
A hero aligned with the Sun widget — moonrise/moonset in big h3 digits, exactly like sunrise/sunset in Sun.jsx, so the two widgets read as a family on the dashboard. Illumination and age move under the phase name ("88 % illuminated · day 12"), and the duplicate "Phase" row disappears.
A "Today" 2×2 grid for the instantaneous state (distance, trajectory, constellation, node) — label above value, which removes the gutter; "(North)" folds into the label ("Northern node").
An "Upcoming" section with real dates — "In 13 days · Sun, Sep 6" instead of "In 13 days" alone, which is consistent with the midnight option meant for comparing with lunar calendars. A small-caps muted section title with a divider is enough to separate the two groups.
Nice-to-have on top: font-variant-numeric: tabular-nums so the digits don't shift on refresh, and rounding 12.06 → 12.1 days (the second decimal is noise at this precision).

Thanks a lot for this — the mockup makes the problem obvious in a way the
screenshot alone didn't. Twelve identical rows really did read like a
spreadsheet, and I like the three-tier structure a lot. I've implemented it.
What went in:
Hero header. Moonrise and moonset are now large figures laid out like sunrise/sunset in Sun.jsx, so the two widgets read as a family. The
"Phase: Waxing" row is gone — the phase name already carries it — and the
age moved under the phase name.
Today's state in a 2-column grid. Distance, trajectory, constellation
and node, label above value. The (North) parenthetical is absorbed into
the label, which now reads "North node" / "South node". Same treatment for
the eclipse kind: "Penumbral eclipse" instead of a trailing parenthesis.
Upcoming events with their real date. "In 13 days · Sun 6 Sep", under a
small-caps section heading with a hairline rule.
Your bonus items:tabular-nums on every numeric value, and the age
rounded to one decimal (12.06 → 12.1).
One deviation from the mockup: I kept "12.1 days" rather than "12th day". The
API returns a continuous age since the last new moon, not a lunar day number,
and the ordinal would have needed a per-language key with a special case at 1.
The interesting part is that adding the absolute date surfaced two real bugs
in the countdown, which the mockup itself hinted at — the sample showed "In 3
days" next to Thu 27 Aug, and those two don't always agree:
diff(now, 'day') counts elapsed hours, not calendar days. The same event
drifted between "in 2 days" and "in 3 days" depending on what time you
looked at the widget, and an event tomorrow morning already said "Today"
late in the evening.
Days were counted, and times formatted, in the browser timezone, while
the server computes everything in the instance timezone (there's even a
comment about it: Gladys images run in UTC). A dashboard opened from
another timezone showed a 23:30 moonrise as 06:30 and could be a full day
off on every countdown.
getMoonState now returns the timezone it computed in, and the widget reads
every date in it, counting calendar days from that midnight. It falls back to
the local timezone when the field is missing, so a front running against an
older server keeps working. Two tests cover the new field.
Same data, same Tabler classes, no new dependency — as you said. Thanks again
for taking the time to mock it up.

This 1-hour skip means a phase that is still upcoming (e.g. full moon in 45 minutes) is treated as already past, so next_full_moon / next_new_moon / the eclipse search jump to the following lunation. With the new absolute dates next to the countdown that shows up as “In 29 days · …” on the evening of the event.
findNextZeroCrossing already handles “exactly now” (distance ≈ 0 is <= 0, bisection lands on from). A 1–2 minute offset, or starting from from itself, is enough to avoid returning the current instant as “next” without dropping the rest of the hour. Same window applies when atMidnight is set and the phase falls between 00:00 and 01:00 local.
The reason will be displayed to describe this comment to others. Learn more.
toFixed(1) always emits a . decimal (12.1), so French/German dashboards show “12.1 jours/Tage” instead of “12,1”. The distance on line 213 has the same class of issue: toLocaleString() with no locale follows the browser language, not user.language.
Passing the Gladys language into both keeps the new “12.1 days” rounding and the km figure consistent with the rest of the UI:
The next node was labelled with the moon's current latitude trend, which
is a different quantity: the moon keeps climbing for about a week after
it has crossed the ascending node, so `ascending` was true while the next
zero crossing was in fact the descending node. The label was wrong for
roughly half of each draconic month.
The node the moon is heading to is the one bringing it back through the
ecliptic plane: it is ascending iff the moon still stands south of it.
Also add two regression tests covering both cases where the old code was
wrong, assert that the perigee is closer than the apogee instead of only
checking the event dates, and replace the deprecated `word-break:
break-word` with `overflow-wrap: anywhere`.

…tdowns
The twelve identical rows of the details column gave no hierarchy: the
Earth-Moon distance weighed as much as the moonrise, and the eye had
nowhere to land. The same data is now laid out in three tiers.
The header shows the phase name, the illuminated fraction and the age,
with moonrise and moonset as large figures — the same layout as the
sunrise/sunset of the sun widget, so both read as a family on the
dashboard. The "Phase: waxing" row is gone: the phase name already says
it. Today's instantaneous values (distance, trajectory, constellation,
next node) move to a compact 2x2 grid, and the upcoming events are
grouped under their own heading, each with its absolute date next to the
countdown so it can be read off a calendar. The node and eclipse kinds
move into their labels instead of trailing parentheses.
Putting the absolute date next to the countdown exposed two bugs in it:
- The countdown was a number of elapsed hours, not of calendar days, so
the same event drifted between "in 2 days" and "in 3 days" depending
on the time of day it was looked at, and an event tomorrow morning
already read "today" late in the evening.
- The days were counted, and the times formatted, in the timezone of the
browser, while the server computes everything in the timezone of the
instance. A dashboard opened from another timezone shifted moonrise by
the difference and could be a full day off on every countdown.
getMoonState now returns the timezone it computed the values in, and the
widget reads every date in it, counting calendar days from that midnight.
The front falls back to the local timezone when the field is absent, so a
front running against an older server keeps working.
The reason will be displayed to describe this comment to others. Learn more.
Rebase onto master looks clean — no functional change from the previous approval, CI is green (front/server tests, Cypress, Docker, codecov patch).
Pierre’s three-tier layout is still in (hero with phase + illumination + age and moonrise/moonset as h3 like the sun card, Today 2×2, Upcoming with absolute dates). Instance-timezone calendar days and next_node_ascending from the sign of ecliptic latitude remain correct.
Not risk:high. Additive dashboard box + authenticated GET /api/v1/house/:house_selector/moon. Local suncalc, no actuation, no new network surface. No DEVICE_FEATURE_* (only generic DASHBOARD_BOX_TYPE.MOON).
Keep needs:human-review + Pierre-Gilles: he asked for this hierarchy and should confirm the screenshot against the mockup before merge. The data-set (sidereal/Lahiri “constellation”, nodes, eclipse type) is a product yes from him already.
Residual (non-blocking, unchanged)
findNextPhase starts one hour after from. A full/new moon (and therefore a lunar eclipse) in the next 59 minutes is skipped. See the inline comment.
Age/distance number format still ignores Gladys language (toFixed(1) → always .; toLocaleString() → browser locale).
Copy:displayDetailsDescription still says the list is “next to” the moon; it now sits below the hero. computeAtMidnightDescription says “visibility” where it means illumination.
Demo mode still mocks GET .../sun but not moon. Harmless unless someone adds a moon box on the demo dashboard.

Description
Adds a Moon dashboard widget, next to the existing Sun one.
It shows the moon as a real photo with the shadow of the current phase drawn over it, along with the phase name and illumination. An optional detail panel lists the distance, the age of the moon, whether it is waxing or waning, its trajectory, the constellation it stands in, moonrise and moonset, and the countdowns to the next full moon, new moon, perigee, apogee, node and lunar eclipse.
Everything is computed locally from suncalc, which was already a dependency: no external API, no API key, no network call at runtime.
Two options in the widget settings:
Server side: new GET /api/v1/house/:house_selector/moon route, backed by gladys.house.getMoonState(), which uses the house coordinates and the instance timezone.
Moon image: moon.png is a crop of the lunar disk from NASA's Scientific Visualization Studio (Moon Phase and Libration, 2025), public domain, resized to 256×256 and masked to a circle (21 KB). Credit and processing details are in front/src/components/boxs/moon/CREDITS.md.
Accuracy: the simplified series used by suncalc gives the right dates but times that can be off by a few hours, which is not visible on a "in 5 days" countdown. The constellation uses the sidereal zodiac (with the Lahiri ayanamsa), like lunar calendars do, not the tropical one. The eclipse search is reliable on the date, less so on the exact type and time.
