Working with dates and times online
Telling the time sounds simple until you have to coordinate across borders, store a date in software, or plan a deadline that respects weekends and holidays. The same moment can be written as a wall-clock time, a UTC timestamp, an ISO 8601 string, a Unix epoch number, or an ordinal day of the year, and each format exists because it solves a different problem. This site brings those formats together with live, accurate tools so you can read the current value, convert between systems, and understand the rules underneath.
Time zones and daylight saving time
Every place on Earth keeps civil time as an offset from Coordinated Universal Time (UTC). Those offsets are mostly whole hours, but a handful of regions use half-hour or even quarter-hour offsets, and many shift by an hour twice a year for daylight saving time. Because governments change these rules more often than people expect, reliable conversion depends on the IANA time zone database rather than fixed numbers. Our world clock, city pages, and timezone converter all read from that database through your browser, so they follow daylight-saving transitions automatically.
Calendar references and date math
Beyond the clock, a lot of everyday planning runs on calendar structure: the ISO week number, the day of the year, leap-year rules, and the count of business days between two dates. These are easy to get subtly wrong by hand, especially around year boundaries and February in leap years. The calendar and calculator pages here compute them precisely, and the explainer articles cover the conventions so you can trust the result and understand where it comes from.
Formats built for machines
Developers and analysts often need a format that sorts correctly and never depends on locale. ISO 8601 (for example, 2026-06-20) and the Unix timestamp are the two workhorses, while Julian day numbers serve astronomy and ordinal dates serve logistics. The format reference pages explain how each one is constructed, when to use it, and how to convert it back to a human-readable date without losing precision.
Frequently asked questions
Common questions about today's date, the current time, and how these tools work.
What is the current date and time?
The live clock at the top of this page shows your current local date and time, read directly from your device using the IANA time zone database in your browser. It updates every second and needs no server request, so it stays accurate even offline. For a full breakdown including UTC, week number, day of year, Julian date, and Unix timestamp, open the Today's Date and Time page.
What time zone does this site use?
The clock uses your own device time zone automatically. We detect it with the browser Internationalization API rather than guessing from your IP address, so daylight-saving transitions and regional offsets are handled correctly. To see a specific place instead, use a city page or the world clock.
What is the difference between UTC and GMT?
GMT (Greenwich Mean Time) is a time zone, while UTC (Coordinated Universal Time) is a global time standard maintained by atomic clocks. They share the same clock reading at UTC+0, but UTC is the precise reference the world synchronizes to, and GMT is the civil time used in places like the United Kingdom in winter.
Why do some countries not change their clocks for daylight saving time?
Daylight saving makes the most sense at higher latitudes, where summer and winter daylight differ sharply. Near the equator the length of the day barely changes, so countries like Singapore, India, and most of Africa keep a fixed offset year-round. Several others, including Russia, Turkey, and most recently Mexico, have abolished clock changes for simplicity.
What is a Unix timestamp?
A Unix timestamp is the number of seconds that have elapsed since 00:00:00 UTC on 1 January 1970, ignoring leap seconds. It is the way most computers store a moment in time because it is a single integer that is easy to compare and convert. Our Unix timestamp tools convert it to and from human-readable dates.
What is the current week number?
Under the ISO 8601 standard the current week is week 25 of 2026. ISO weeks start on Monday and the first week of the year is the one containing its first Thursday, which is why the ISO week number can differ from the simpler US convention that starts weeks on Sunday.
How accurate is the time shown here?
The displayed time is exactly as accurate as your device clock, since all calculation happens locally in your browser. Modern phones and computers sync to network time servers automatically, so they are usually accurate to well within a second. We add the correct time zone and daylight-saving rules on top of that base reading.
Do these tools work without an internet connection?
Once a page has loaded, the clocks, converters, and calculators run entirely in your browser with no further network requests, so they keep working offline. Only the first page load needs a connection. This local-first design also means we never see or store the dates and times you enter.
How this site is organized
The site is organized around clear user jobs. A live-reference page handles current-value intent. Topic hubs handle broader questions like date formats, calendar systems, or time zones. Dedicated calculators and converters exist only when the task changes enough to deserve a separate page. Pages are added because they solve a distinct user intent, not to chase a keyword variation.
