Cron Next Run Calculator

Cron syntax is compact but easy to get subtly wrong — a misplaced field, an unexpected OR between day-of-month and day-of-week, or a step value that doesn't line up the way you expected. Rather than waiting to see if a scheduled job actually fires at the right time in production, paste the expression here first and confirm the exact upcoming run times before you deploy it.

This is especially useful for schedules that run infrequently — a monthly or yearly cron might not reveal a mistake for weeks, by which point a missed run can be a real incident.
