## Tools (7)

- `find_full_moons`: Returns every full Moon of a calendar year with its date and time in a time zone, its traditional name such as Wolf Moon or Harvest Moon, its distance from Earth and whether it is a supermoon or a Blue Moon. Years run from 1900 to 2100.
- `get_moon_calendar`: Returns every day of a month with the Moon's phase and percent lit at 12:00 local time, and the exact times of that month's new Moon, first quarter, full Moon and last quarter in a time zone.
- `get_moon_distance`: Returns the Moon's distance from Earth in kilometres and miles at a date and time, its apparent width, the previous and next perigee and apogee, and the next full Moon's distance with whether that full Moon is a supermoon.
- `get_moon_phase`: Returns the Moon's phase, percent lit, lunar age and waxing or waning direction right now, at 12:00 on a date, or at a clock time on a date, in a time zone or city. Also returns the next new Moon, first quarter, full Moon and last quarter, the previous full Moon and the moment the phase name changes. Dates run from 1900 to 2100.
- `get_moonrise_moonset`: Returns moonrise, moonset and the Moon's highest point on a local date for a city from the website's list of world cities, or for any latitude and longitude, with compass directions and the Moon's phase that day. Also returns when the Moon is up after dark and, for today, where the Moon is right now. Times are in the place's own time zone.
- `get_moon_sign`: Returns the zodiac sign the Moon is in at a date and local time, in a time zone or city, with its degree in the sign and the next sign change. Without a time it returns every sign the Moon is in during that date. The tropical or the Lahiri sidereal zodiac can be chosen.
- `list_eclipses`: Returns the lunar and solar eclipses of a calendar year with their type, the time of greatest eclipse in a time zone, the contact times of lunar eclipses, where solar eclipses are greatest and which of 16 major world cities see each one. The type filter limits the list to lunar or solar eclipses.
