Cron syntax is five small fields, and it is easy to get one subtly wrong, then wonder for weeks why a job never fired. Paste an expression and this spells out in plain words when it runs and lists the next few run times, so you can confirm the schedule before you ship it.

Good to know

Five fields, in orderMinute, hour, day of month, month, day of week. A classic mistake is mixing up day of month and day of week.
Steps, ranges and listsA slash sets a step like every 15 minutes, a dash sets a range, and a comma lists separate values.
It runs in the server timezoneCron fires on the host clock, so the next runs shown may not match your local time. Mind the offset.
Five fields, not sixStandard cron has five fields; some platforms add a seconds field at the front, so check which form yours expects.
