Date and Time Tools
This site helps you check the current date and time, compare clocks in different cities, and calculate dates without treating every month as 30 days. City times use IANA timezone identifiers such as Europe/London. The offset you see is read for this exact moment, including daylight saving when it applies.
How Current Local Time Is Calculated
The large clock on this page starts with the server’s current time, then follows your browser timezone when JavaScript is available. The IANA name shown (for example Europe/London) comes from Intl.DateTimeFormat().resolvedOptions().timeZone. City pages do not trust a stored UTC offset; they convert the same instant into that city’s zone.
Understanding Timezones and UTC Offsets
UTC is the reference scale civil clocks are based on. A positive offset such as UTC+01:00 means local time is ahead of UTC. Offsets change when a region starts or ends daylight saving, so a “five-hour gap” between two cities is not guaranteed all year.
How Daylight Saving Time Affects Time Comparisons
The United Kingdom and the United States change clocks on different dates. For a few weeks in March the gap between London and New York is often four hours instead of five. Some places, including much of Arizona and Hawaii, do not change clocks at all.
Calculate the Difference Between Dates
The date-difference tool counts calendar midnights between two dates. You can include the end date if you need an inclusive count. Weekdays are Monday to Friday. Adding one month uses calendar months: 31 January plus one month is the last day of February.
Calculate Days From Today
Popular phrases such as “90 days from today” have their own pages. Unusual amounts still calculate, but those result URLs are marked noindex so the site does not create an infinite set of near-duplicate pages.
Compare Time Between Cities
The comparison tool converts one instant into each selected city. Use it to plan a call during overlapping working hours (09:00–17:00 local) rather than subtracting a remembered offset.
Calendars, Leap Years and Week Numbers
Calendars use ISO weeks (Monday start). A leap year has 366 days when it is divisible by 4, except century years, which must also be divisible by 400. Day-of-year figures are ordinal calendar dates (YYYY-DDD), not astronomical Julian day numbers.
