What is today's date and week number?
Today is Monday, October 26, 2026. It is day 299 of the year and falls in ISO week 44, counted from Monday to Sunday. The date and week change at midnight in your own time zone, so someone in Tokyo can already be on the next day while you are still on this one.
Week numbers follow the ISO 8601 rule: week 1 is the week with the year's first Thursday. Most of Europe uses this rule for planning, while many US calendars start the week on Sunday. The week number for today page shows the full list for the year, and the yearly calendar has every month with holidays.
What time zone am I in?
Your time zone is detected from your IP address and shown in the clock panel above, with its name, abbreviation and UTC offset. If you are in New York in summer, for example, you see Eastern Daylight Time, UTC−4. The page also says whether your zone uses daylight saving time and lists today's sunrise and sunset for your city.
IP location is usually right to the city level, but a VPN or a mobile network can place you somewhere else. Set your city once with "Make default" and Time Now remembers it on that browser. The your time zone page explains the offset in more detail.
Current time in major cities
The world clock under the main clock shows New York, Los Angeles, London, Paris, Dubai, Mumbai, Tokyo and Sydney, each with the hours ahead of or behind you. In winter, 9:00 AM in New York is 2:00 PM in London (GMT), 7:30 PM in Mumbai (IST) and 11:00 PM in Tokyo (JST). In summer London stays at 2:00 PM, while Mumbai and Tokyo are one hour earlier.
For a full list by offset, open world time zones. For short codes like CET, AEST or PDT, the time zone abbreviations list gives the full name, offset and the places that use each one.
When do the clocks change?
In the United States and Canada clocks go forward one hour on the second Sunday of March and back on the first Sunday of November, at 2:00 AM local time. The EU and the UK change on the last Sunday of March and the last Sunday of October, at 01:00 UTC. Because the two sides change on different weekends, New York is 4 hours behind London instead of 5 for a few weeks each spring and autumn.
In the southern hemisphere the calendar is reversed: south-east Australia uses summer time from the first Sunday of October to the first Sunday of April, and New Zealand starts a week earlier, on the last Sunday of September. Most of Asia, Africa and South America never change their clocks. The daylight saving time page lists each year's dates by country.
How accurate is the time on Time Now?
The clock on Time Now is usually within about 0.1 seconds of the server time. When the page loads, your browser asks our server for the time several times, measures how long each request takes and corrects for that delay. The result is the line under the clock above, such as "Your clock is 0.2 seconds slow".
Device clocks drift because their quartz crystal runs slightly fast or slow, and computers only resync now and then. Windows, for example, checks time.windows.com about once a week on a home PC. Time zone and daylight saving rules on Time Now come from the IANA Time Zone Database, the same data phones and operating systems use.
How to use Time Now
Time Now works without an account. Click a city name and choose "Make default" to keep it on the home page. Switch between 12-hour and 24-hour format in the settings, and add favorite cities to see them under the clock at the top of the page. To find the overlap between two places, use the time zone converter. More tips are on the how to use Time Now page.
Frequently asked questions
Why is my computer clock wrong?
Most wrong computer clocks come from one of three causes: automatic time sync is turned off, the time zone setting is wrong, or the motherboard battery is weak so the clock resets after a shutdown. A clock that is off by exactly one hour usually has the right time but the wrong time zone or an outdated daylight saving rule.
Is the time on my phone accurate?
A phone with automatic date and time turned on gets its time from the mobile network or from internet time servers, so it is usually within a second of the correct time. If you set the time by hand, the phone stops syncing and can drift by several seconds a month.
Does Time Now adjust for daylight saving time?
Yes. Every clock on Time Now applies the daylight saving rules of its location from the IANA Time Zone Database, including countries that have dropped DST, such as Mexico in 2022. You never need to add or remove an hour yourself.
