About this tool

TimeToolsLab helps you answer everyday time and date questions in your browser. Find what time it was hours or minutes ago, see how long remains until a chosen clock time, add or subtract days, weeks, months, or years from a date, and calculate a future time from a duration.

Choose your time zone and switch between 12-hour and 24-hour formats. Live countdowns keep the remaining time up to date, and you can copy results for use in a message or plan. Popular question pages let you go straight to calculations such as 8 hours ago, how long until 3 PM, or 70 days from today.

The tools are free to use, require no signup or installation, and run calculations in your browser. Use TimeToolsLab on desktop or mobile whenever you need a quick time or calendar answer.
