About Today's Date
This page shows today's date using your device's local time and timezone. It displays the full date, day of the week, current time, ISO week number, day of the year (1-365/366), days remaining in the year, and whether it's a leap year. Below the main display, you'll find today's date in 8 common formats — each with a copy button — plus countdowns to the nearest major holidays and events.
Date Formats Explained
- DD/MM/YYYY: Day-month-year, used in the UK, Europe, Australia, and most of the world. Example: 15/03/2026
- MM/DD/YYYY: Month-day-year, used primarily in the United States. Example: 03/15/2026
- YYYY-MM-DD: ISO 8601 standard, used in computing, science, and East Asia. Example: 2026-03-15. This format sorts correctly in alphabetical order.
- DD Month YYYY: Long format common in formal writing. Example: 15 March 2026
- Unix timestamp: Seconds since 1 January 1970 00:00:00 UTC. Used in programming and databases.
How Week Numbers Work
ISO 8601 defines week 1 as the week containing the first Thursday of the year. Weeks start on Monday. This means 1 January can fall in week 52 or 53 of the previous year. Most European countries, businesses, and software use ISO week numbers. The US typically uses a Sunday-start week system where week 1 begins on 1 January regardless.
Leap Year Rules
A leap year has 366 days (with 29 February). The rules: divisible by 4 = leap year, UNLESS divisible by 100 = not a leap year, UNLESS divisible by 400 = leap year. So 2024 was a leap year (divisible by 4). 1900 was NOT (divisible by 100). 2000 WAS (divisible by 400). The next leap years: 2028, 2032, 2036.

Time Zones and UTC
UTC (Coordinated Universal Time) is the global time standard. The UK uses GMT (UTC+0) in winter and BST (UTC+1) in summer. The date shown on this page uses your device's local timezone. When communicating dates internationally, specify the timezone or use UTC to avoid confusion. ISO 8601 format (YYYY-MM-DD) combined with UTC time is the clearest way to express a date and time globally.

- Gregorian: The international standard, introduced by Pope Gregory XIII in 1582. Used by this page.
