sun-and-moon
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.
npx skills add mohitagw15856/pm-claude-skills --skill sun-and-moon --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.

Where does this skill come from?
From mohitagw15856/pm-claude-skills, a repository with 1,255 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
