29 December

29 December is the 363rd day of the Gregorian calendar year (364th in leap years). Two days remain in the year. The Gregorian calendar is the dating system used by most of the world.

The date falls in the final week of the year, a period when many countries observe seasonal holidays. In the Northern Hemisphere it is winter; in the Southern Hemisphere it is summer, as the seasons are opposite in the two hemispheres.

Calendar and calculation

The Gregorian year has 365 days, with an extra day added to February in leap years. This means 29 December is always the second-to-last day before 31 December. The day of the week on which it falls changes each year.

Use of other calendar systems

Many countries and communities use calendars parallel to the Gregorian calendar, such as the Islamic calendar, which is based on the lunar cycle. For this reason, 29 December does not correspond to a fixed date in other calendar systems; the date varies from year to year.

List of events

Like any day in the calendar, 29 December is marked by historical events, births, and deaths. Some encyclopedias maintain lists of these; such lists are selective in nature and vary across languages and regions.
