The Western Pacific Regional Fishery Management Council has produced traditional
lunar calendars for Guam since 2007. The intent is to enhance community involvement in
fishery management.
In addition to sharing traditional and cultural knowledge about fishing, the 2023
Fanha’aniyan Pulan CHamoru (Chamorro Lunar Calendar) provides information about
different ways that fisheries are monitored and kept healthy. The lunar months, moon
phases and traditional calendar months are given in Chamorro, the native language of
the indigenous people of Guam. The moon phases in this calendar are for Hagåtña as
calculated by the HM Nautical Almanac (astro.ukho.gov.uk/websurf). The tide charts
with moon rise and set times are in Chamorro Time for Hagåtña and were provided by
OceanFun Publishing, NZ.
