find_full_moons Read-only

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.

yearinteger

Calendar year from 1900 to 2100; the current year when omitted.

timeZonestring

IANA time zone name such as America/New_York or Asia/Tokyo; UTC when omitted.
