Cron Expression Parser

The Cron Expression Parser translates a cron schedule into plain English and previews the upcoming run times, so you can confirm that an expression does exactly what you intend before you deploy it. Enter a pattern such as */5 * * * * and it tells you, in words, that the job runs every five minutes.

Developers and system administrators use it to write and sanity-check the schedules behind cron jobs, CI pipelines and other recurring tasks. Seeing the next several execution times spelled out catches subtle mistakes — like a job that fires far more or far less often than expected — that a raw expression would otherwise hide until it misbehaved in production.

Parsing runs in your browser with nothing uploaded, so it is instant and private. With no install and no account, it is a quick safeguard you can run any time you are about to commit a new or edited schedule.
