How this service works
Moon phase name, illuminated percentage and age in days for any date, plus the next new and full moon (UTC). Computed locally from the mean synodic month. Use for calendars and night-sky planning.
Output
A JSON object containing today's date, the named moon phase (e.g. 'Waning Crescent'), the moon's age in days within the current cycle, the illumination percentage, the datetime of the next new moon, and the datetime of the next full moon.
Example use cases
Stargazing night planner
“I want to go stargazing this weekend — what's the current moon phase and how much of the moon is illuminated tonight? And when's the next new moon so I can plan for darker skies?”
Gardening by lunar calendar
“I follow lunar gardening and want to know what moon phase we're in right now and how many days old the moon is, so I know whether to plant or harvest today.”
Werewolf / fiction writing detail
“I'm writing a scene set tonight and need the accurate real moon phase — what is it, what percentage is it lit, and when's the next full moon?”
