The determination of the date of the Christian celebration of the Resurrection in 2002 is achieved through a complex calculation rooted in both lunar cycles and the vernal equinox. It does not fall on a fixed calendar date, requiring astronomical observations and ecclesiastical rules to converge upon a specific Sunday.
Understanding the specific date of observance in any given year provides a fixed point in historical calendars and allows for accurate temporal referencing of events. It also plays a role in academic research, genealogy, and the study of cultural traditions linked to this religious observance. Furthermore, the ability to pinpoint its occurrence is vital for organizations and individuals planning events or commemorating anniversaries tied to that period.
