How these calendars relate

The Gregorian calendar most of the world uses for civil purposes is purely solar. Many cultural and religious calendars are lunar (Islamic) or lunisolar (Hebrew, Chinese) β€” meaning their dates drift relative to the Gregorian year. The pages above pin each one to specific Gregorian dates so you can plan ahead; the Islamic and Persian calendars are available for 2026 and 2027.
