What it does
Sun And Moon is an agent skill from mohitagw15856/pm-claude-skills. Get sunrise, sunset, golden hour, day length, and moon phase for any location with zero API keys — sunrise-sunset.org and Open-Meteo via curl, times converted to local. Use when asked when is sunset today, golden hour for a photo shoot, how long is the day, what's the moon phase tonight, or sun times for a date and place. Produces the sun/moon times in the user's local zone (the UTC trap handled), the photography windows, and the rerunnable command.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it
- Asked when is sunset today
- Golden hour for a photo shoot
- How long is the day
- Whats the moon phase tonight
Example prompts
- “/sun-and-moon”

What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
geocoding-api.open-meteo.comapi.sunrise-sunset.orgapi.open-meteo.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Sun And Moon loads about 1.2k tokens when it runs. Until then it costs about 117 tokens; SKILL.md has 558 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Get sunrise, sunset, golden hour, day length, and moon phase for any location with zero API keys — sunrise-sunset.org and Open-Meteo via curl, times converted to local. Use when asked when is sunset today, golden hour for a photo shoot, how long is the day, what's the moon phase tonight, or sun times for a date and place. Produces the sun/moon times in the user's local zone (the UTC trap handled), the photography windows, and the rerunnable command.
Sun and Moon Skill
Sunset time drives photo shoots, hikes, drone flights, fasting schedules, and the eternal "do we have time before dark" — and two keyless services answer it for any coordinates and date. This skill fetches, then does the two things the raw response doesn't: converts UTC to the place's local time (the classic wrong-answer generator in this domain), and derives the windows people actually want — golden hour, blue hour, usable daylight.
What This Skill Produces
- The times — sunrise, sunset, solar noon, twilight bounds — in the location's local time, labeled
- The derived windows — golden hour (~the hour after sunrise / before sunset), blue hour, day length and its current trend
- Moon phase — tonight's phase with the plain-language name
- The command — exact curl, rerunnable
Required Inputs
Ask for these if not provided:
- Location — lat/lon or a place name (geocode via
https://geocoding-api.open-meteo.com/v1/search?name=Lisbon&count=1) - The date — today default; any date works (both services take past and future dates)
- The real question — a shoot wants golden hour, a hike wants last-light, "is it a full moon" wants the phase — lead with theirs
Framework: The Calls and the UTC Trap
- sunrise-sunset.org — primary:
curl -s "https://api.sunrise-sunset.org/json?lat=35.68&lng=139.69&formatted=0&date=2026-07-19"→ ISO times includingcivil_twilight_begin/endandday_length(seconds). Alwaysformatted=0and always convert: the times are UTC, and serving Tokyo's sunset as "09:57" is this domain's signature failure. Get the zone from the world-clock pattern or Open-Meteo'stimezone=auto. - Open-Meteo — fallback and bulk:
curl -s "https://api.open-meteo.com/v1/forecast?latitude=35.68&longitude=139.69&daily=sunrise,sunset,daylight_duration&timezone=auto&forecast_days=7"—timezone=autoreturns local times directly (safer), and a week in one call for trend questions. - Moon phase:
curl -s "wttr.in/Tokyo?format=%m"→ the phase emoji; for the name and precision, compute from the synodic cycle (29.53 days from a known new moon) and say "waxing gibbous, ~87% illuminated" — labeled as computed. - The derived windows: golden hour ≈ sun within 6° of horizon — practical answer: the ~60 minutes after sunrise and before sunset; blue hour ≈ civil twilight. State them as ranges ("golden hour: 18:40–19:45"), which is what the photographer books.
- Trend and context: day_length compared across the week answers "are days getting longer"; near solstices, note the daily change is seconds, near equinoxes minutes — precision theater either way is avoided.

Output Format
Sun & Moon: [location] — [date]
[The lead answer: "Sunset 19:45 local; golden hour 18:45–19:45."]
| Event | Local time |
|---|---|
| [Sunrise · solar noon · sunset · civil twilight · day length] |
Moon: [phase name, ~illumination] [Trend line if asked: day length vs. yesterday/next week]
Source: [sunrise-sunset.org / Open-Meteo] · times local to [zone] · rerun: [exact curl]
Quality Checks
- Every time is explicitly local to the location, with the zone named
-
formatted=0was used and UTC→local conversion applied (or timezone=auto took care of it) - The asked-for window (golden hour, last light) leads the answer
- Moon phase carries its name, not just an emoji
- Computed values (moon %, golden hour) are labeled as derived
Anti-Patterns
- Do not serve UTC times as local — the single failure mode this skill exists to prevent
- Do not answer from memory — sun times shift daily and by latitude dramatically
- Do not give bare sunset when the question was a photography or safety window
- Do not overstate moon precision — phase and rough illumination, not fake decimals
- Do not ignore polar edge cases — high latitudes in summer/winter return no-sunset/no-sunrise; report that as the (correct) answer, not an error
Example Trigger Phrases
- "When is sunset today?"
- "When's golden hour for my shoot?"
- "How long is the day?"
- "What's the moon phase tonight?"
