Will timers keep running if I switch tabs or lock my screen?

Yes. Timers continue running while you switch tabs, and the alarm will still trigger when time is up (depending on your browser/device settings).

Can I use the stopwatch for lap and split times?

Yes. Press Lap while the stopwatch is running to record a split without stopping the clock. Each lap is logged with its individual time and cumulative total.

What is the Pomodoro technique?

Pomodoro uses focused work sessions (often 25 minutes) followed by short breaks to help maintain productivity.

Can I set an alarm clock in the browser?

Yes. You can set alarms with customizable sounds and labels.

Do these tools support sound notifications?

Yes. Timers and the Alarm Clock play audio alerts when time is up. Allow browser notifications in your settings to ensure sound plays even when the tab is in the background.

How do I convert between time zones?

Use the Time Zone Converter to compare times between locations, and the World Clock to view multiple cities at once.

What’s the difference between Unix timestamp and a normal date?

A Unix timestamp is the number of seconds since Jan 1, 1970 (UTC). It’s commonly used in programming and APIs.

How do I find the week number for a date?

Use the Week Number Calculator to get the week number and navigate between weeks.
