Today's Date in Every Format
The same moment written across the formats you'll encounter in software, paperwork, and international correspondence. All based on your device's local clock.
- ISO 8601
- US (MM/DD/YYYY)
- European (DD/MM/YYYY)
- Japanese (YYYY年M月D日)
- RFC 2822 (email headers)
- Unix timestamp
- Day of year / total
- ISO week / year
- Julian day number
Not sure which format to use? ISO 8601 (YYYY-MM-DD) is the safest for databases, filenames and any cross-border document — it sorts correctly as text and has no day/month ambiguity. US and European short formats are the source of most international misreadings (03/04/2026 means March 4 in the US but April 3 in Europe).

What Day Is It Today?
Today's full date is shown at the top of this page, drawn directly from your device's clock and refreshed each time you visit. The display includes the weekday, month, numerical date and year, plus yesterday and tomorrow's dates for quick reference. It stays accurate across midnight automatically, and after daylight-saving transitions — your operating system handles the clock change, and this page reads whatever value is current.
Beyond the date itself, the cards above show the day-of-year number (1–365 or 1–366 in a leap year), the current ISO week number, your detected IANA time zone, the current Unix timestamp, how much of the day has already elapsed, how many days remain in the year, the current calendar quarter, and whether this year is a leap year. The "Today in Every Format" panel renders the same date in ISO 8601, US, European, Japanese, RFC 2822 email-header and Julian Day Number formats — useful when you're copying a date into a form, filing a document, or writing code that expects a specific layout.
Why the date looks different in different places. There's no single "correct" way to write a date. The United States writes 4/17/2026 (month first); most of Europe and Latin America writes 17/4/2026 (day first); ISO 8601 — the only international standard — writes 2026-04-17 (year first). For anything that will be read outside a single country, the ISO form is safest: it sorts correctly as plain text, has no day/month ambiguity, and is accepted by every modern database and programming language. Spreadsheets, filenames, and version-control tags all benefit from it.
How calendar math actually works. A common year has 365 days — that's 52 weeks and one extra day, which is why every date shifts forward one weekday each year (e.g. if today is Friday, the same date next year will be Saturday). Leap years add a 366th day at the end of February, shifting dates after Feb 29 by two weekdays instead of one. Months run 28, 29, 30 or 31 days; the phrase "30 days from now" is unambiguous, but "one month from now" can land anywhere from Feb 28 to March 3 depending on the starting date. When deadlines matter, our Days Calculator and Business Days Calculator remove the guesswork by counting exact day increments on your chosen rule (calendar days vs. Mon–Fri only).
How time zones and DST intersect. The world runs on ~400 IANA-maintained time zones — more than the textbook "24 hourly zones" because countries adjust their rules for politics, geography and DST history. India (UTC+5:30) and Nepal (UTC+5:45) don't fit neatly into the hourly grid. Daylight saving time is used in North America, Europe, parts of Oceania and a few other regions, shifting clocks forward one hour in spring and back in autumn — which means the offset between a DST region and a non-DST region (like most of Asia or Africa) changes twice a year. Our Time Zone Converter bakes the selected date into every calculation, so the result reflects whichever offset was actually in effect at that moment.

Frequently Asked Questions
A common year has 365 days; a leap year has 366. The extra day is February 29, which appears in years divisible by 4 — with the century exception: years divisible by 100 are only leap years if also divisible by 400. So 2024 was a leap year, 2000 was, but 1900 was not. A year of 365 days equals exactly 52 weeks and 1 extra day, which is why a given date shifts forward one weekday each year (two in leap years, for dates after February 29).
Under ISO 8601, weeks start on Monday and week 1 of a year is the week containing that year's first Thursday — equivalently, the week containing January 4. This means some dates in early January can belong to week 52 or 53 of the previous year, and late-December dates can belong to week 1 of the next year. Most years have 52 ISO weeks, but years where January 1 falls on a Thursday (or Wednesday in a leap year) have 53 weeks. The US "broadcast" week numbering system is different — it starts weeks on Sunday and counts week 1 as the week containing January 1.
A leap year has 366 days instead of 365, with the extra day added to February. The rule: divisible by 4, unless also divisible by 100, unless also divisible by 400. The rule exists because Earth's orbit takes ~365.2422 days — slightly longer than 365 — so a leap day every four years almost (but not quite) corrects the drift. The century exception shaves off the remaining error. Without it, the calendar would drift three days every 400 years. The Next Leap Year page shows the exact countdown to the upcoming February 29.
The seven-day week is one of the few time units with no astronomical basis (unlike days, months, or years). It originates with Babylonian astronomers, who grouped days by the seven "wandering stars" visible to the naked eye — the Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn. Those assignments survive in English weekday names via Roman and Germanic translation: Saturday/Saturn, Sunday/Sun, Monday/Moon, then Tiw (Tuesday), Woden (Wednesday), Thor (Thursday) and Frigg (Friday). Several civilisations have tried to replace the seven-day week — revolutionary France had a 10-day week, the Soviet Union experimented with 5- and 6-day weeks in the 1930s — but all reverted.
Three conventions dominate: MDY (03/04/2026 = March 4) used in the US; DMY (03/04/2026 = 3 April) used in most of Europe, Latin America and much of Asia; and YMD (2026-03-04) used in China, Japan, Korea and the ISO 8601 international standard. The US convention likely traces to 18th-century British usage that Britain itself later abandoned. For anything cross-border — databases, contracts, filenames, international forms — ISO 8601 (YYYY-MM-DD) is the safest: it sorts correctly as plain text and has no ambiguity.
GMT (Greenwich Mean Time) is a time zone — the civil time in the UK during winter. UTC (Coordinated Universal Time) is a time standard, the reference against which all other zones are defined. They are almost identical in everyday use: UTC = GMT to within a second, always. The difference is how they're maintained. GMT is based on Earth's rotation and the position of the Sun over Greenwich; UTC is atomic-clock time, nudged occasionally with leap seconds to stay aligned with GMT. UTC officially replaced GMT as the world's time reference in 1972.
A Unix timestamp is the number of seconds elapsed since January 1, 1970, 00:00:00 UTC — a moment known as the "Unix epoch". It was chosen by the original Unix operating system developers and has become the standard time representation across nearly every programming language and database because it's a single integer that doesn't depend on time zones, DST, or locale. The "Year 2038 problem" refers to the fact that 32-bit signed integers overflow at 2,147,483,647 seconds — January 19, 2038 at 03:14:07 UTC — which is why modern systems store timestamps in 64-bit.
Most time zones are offset from UTC by whole hours, but not all. India (UTC+5:30) chose a single national offset at independence in 1947 rather than split the country into two zones. Nepal (UTC+5:45) is aligned to Kathmandu's actual solar time. Iran (UTC+3:30), Afghanistan (UTC+4:30), Myanmar (UTC+6:30) and parts of Australia (UTC+9:30 for South Australia, UTC+8:45 for Eucla) use other half- and quarter-hour offsets. The most unusual is the Chatham Islands (UTC+12:45). These exist because time zones are ultimately political decisions — countries pick the offset that best fits their geography, economy, and neighbours.
The one-hour shift is arbitrary — early proposals (including Benjamin Franklin's 1784 satirical letter and William Willett's 1907 pamphlet) suggested smaller, gradual shifts. When Germany became the first country to adopt DST in 1916, it picked a single one-hour change for simplicity, and every subsequent country followed. A handful of regions have experimented with 30-minute shifts (Lord Howe Island in Australia still does) but these are exceptions. Not every country observes DST — most of Asia, Africa and South America keep a single offset year-round, as do Arizona and Hawaii in the US.
