New and full moons

New moons, full moons and both quarters across a window of dates. Solved on the Moon's elongation from the Sun rather than on the Moon's position alone. That distinction is not pedantic: a full moon is the Moon 180 degrees from where the SUN is now, and using the Moon's longitude by itself drifts by up to a day over a year. Each entry gives the sign of both the Moon and the Sun at that moment. Filter with `phases` if you only want new and full.

Test Request

Request fields

Field	Type	Required	Notes
date_time	string (date-time)	required	The moment to calculate for, ISO 8601. ALWAYS include an offset or a trailing Z - a value with no zone is read as Asia/Kolkata (UTC+05:30), not UTC, and can return the previous day's result with a 200. '2026-09-01T06:00:00Z' and '2026-09-01 06:00:00' are different instants and give different answers.
end_date_time	string (date-time)	required	End of the window.
bodies	array	optional	Defaults to all eleven. Narrow it to keep responses small.
keys	array	optional	Which calculations to return, as a list of names. See the key table for this endpoint; an unrecognised name rejects the whole request. One call costs one credit however many keys you ask for, so request everything you need at once rather than making several calls.
latitude	number (double)	optional	Latitude of the place, in decimal degrees. Positive is north, negative is south. Example: 26.9124 for Jaipur, 40.7128 for New York. Minutes and seconds are not accepted - convert first.
longitude	number (double)	optional	Longitude of the place, in decimal degrees. Positive is east, negative is west. Example: 75.7873 for Jaipur, -74.0060 for New York. Note the sign: a missing minus puts New York in China.
phases	array	optional	Defaults to all four. Ask for new_moon and full_moon only if you do not need the quarters.
timezone_as_float	number (double)	optional	UTC offset of the place, in hours, as a decimal. Example: 5.5 for India (UTC+05:30), -5 for New York in winter, 5.75 for Nepal. This is NOT validated against date_time - if the two disagree you get a successful response for the wrong moment, so derive both from the same source. Use the offset in force on that date, not today's: a summer birth in a country with daylight saving needs the summer offset. min -12 · max 14
