One hour ago is the offset people use for a meeting that just ended, a parking ticket window, a “started an hour ago” workout, or a log line that should match the previous hour. It is close enough to now that counting by hand still goes wrong when the hour wraps past midnight.

How “1 hour ago” is calculated

The page subtracts exactly 60 minutes from your current local time. If it is 00:20, one hour ago is 23:20 yesterday. The date under the clock updates with that wrap, and the timezone label tells you which local clock was used.

If one hour is too coarse, try 30 minutes ago or 45 minutes ago. If you are reconstructing a longer gap, jump to 2 hours ago or 3 hours ago from the links on this page.

Browse hours ago, minutes ago, from now, or the guides if you need the method instead of a single offset.
