When’s Easter? — whens easter explained

Introduction: Why ‘whens easter’ matters

Many people ask ‘whens easter’ each year because the date moves and affects travel, school holidays, religious observances and public holidays. Understanding how the date is set helps households, businesses and places of worship plan ahead. The question is both practical and cultural: Easter is central to Christian calendars and widely influences secular schedules across the UK and beyond.

Main body: How the date of Easter is calculated

The basic rule

For Western Christian churches (including most Protestant denominations and the Roman Catholic Church), Easter is celebrated on the first Sunday after the Paschal Full Moon that occurs on or after 21 March. The 21 March date is treated as the fixed date of the vernal equinox for ecclesiastical purposes. Because the Paschal Full Moon is determined by an ecclesiastical approximation rather than the astronomical full moon, the resulting date can vary year to year.

Date range and terminology

Because of this rule, Western Easter can fall no earlier than 22 March and no later than 25 April. The procedure used to compute the date is historically known as the Computus. Practical consequences in the UK include the timing of Good Friday and Easter Monday bank holidays, school breaks and many community events.

Differences with Orthodox Easter

Eastern Orthodox churches use a related rule but base calculations on the older Julian calendar, and also require Easter to occur after Jewish Passover in many traditions. As a result, Orthodox Easter often falls later than Western Easter and sometimes in early May on the Gregorian calendar. The two traditions coincide occasionally, but differences remain common.

Conclusion: What readers should do

If you are asking ‘whens easter’ for planning, the simplest approach is to check a reliable calendar or an official source for the specific year. For long-term planning, remember Western Easter falls between 22 March and 25 April; Orthodox dates may be later. Employers, schools and event planners should confirm dates early to avoid clashes, and travellers should book with the flexible cancellation options where possible during the busy Easter period.
