What it does

See exactly when a scheduled job will run before you trust it. Paste a cron schedule, a calendar repeat rule or a GitHub Actions schedule, or type something like "every weekday at 9am", and it explains the schedule in plain English, lists the next 25 run times and shows a calendar heat map of up to a year. Pick two time zones to compare them side by side, including what happens on daylight-saving change days.

Good to know

It understands only part of the calendar repeat-rule standard, and the plain-English typing handles common phrasings rather than any sentence.
