Time & Date Tools
Work with timezones, dates, countdowns, and chronological calculations. All tools run entirely in your browser: free, instant, and with no sign-up.
Timezone Converter
A timezone converter translates a date and time from one time zone to another, automatically accounting for UTC offsets and daylight saving time rules. Pick a source and destination time zone, enter a time, and this free tool instantly shows the equivalent local time, ideal for scheduling meetings, calls, and travel across the world.
Countdown Timer
A countdown timer shows exactly how much time remains until a future date or event, updating live in days, hours, minutes, and seconds. Set an end date, give your countdown a name, and this free tool tracks the remaining time, perfect for birthdays, holidays, product launches, exams, and project deadlines.
Date Calculator
A date calculator performs arithmetic on calendar dates: it finds the exact difference between two dates in years, months, and days, or adds and subtracts a chosen amount of days, weeks, months, or years from a starting date. This free tool handles leap years and month-length differences automatically, so results are always accurate.
Unix Timestamp Converter
A Unix timestamp (epoch time) is the number of seconds elapsed since January 1, 1970 at 00:00 UTC. This free converter turns any Unix timestamp into a human-readable date and time, and converts dates back into timestamps. It automatically detects seconds versus milliseconds and supports negative timestamps for dates before 1970.
Stopwatch
An online stopwatch measures elapsed time with millisecond precision directly in your browser, no app or installation needed. Start, pause, and reset the timer with a click, and record unlimited lap times to compare splits. It is ideal for workouts, races, cooking, studying, presentations, and any task you need to time.
