When is that holiday?

What this date guide covers

This index collects major religious and cultural holidays whose Gregorian dates are commonly searched because they move, span more than one day, or differ by tradition. Each linked page explains the next date, the upcoming multi-year pattern, and the calendar system behind the observance. The goal is practical: help you schedule travel, school calendars, content plans, customer support cover, and cross-border meetings without treating every holiday as a fixed-date event.

The date table is generated from ClockOrbit's 2026-2035 religious holiday calendar. For many observances, the civil date is predictable once the calendar calculation is known. For others, local moon sighting, government proclamation, denomination, or country rules can affect the public holiday date. Where that distinction matters, the individual holiday page should explain the assumption rather than hiding it behind a single unexplained date.

How to read the results

Use these pages as a reliable planning starting point, then confirm official closures with the country, state, school, employer, or religious community involved. That is especially important for payroll deadlines, exams, shipping cutoffs, and events that depend on local observance rather than only the calendar date.
