Cron expression helper

Common use cases

• Decode a crontab line before deploying: confirm minute, hour, day, month, and weekday fields.
• List the next UTC run times to align with log timestamps and job monitors.
• Compare a human-readable summary against what you meant (for example daily vs hourly).

Common mistakes to avoid

• Assuming cron uses your local timezone

  Schedules are often interpreted in the server’s timezone. This page shows next runs in UTC—adjust mentally for your deployment zone.

• Mixing up day-of-month and weekday

  When both fields are set, behavior can follow either field depending on the cron implementation—verify on the target system.

• Using six-field strings when five are standard

  This helper expects the common five-field cron (minute through weekday). Systems with seconds need a different format.
