Cron expression tester0 */2 * * *

What does 0 */2 * * * mean?

Every 2 hours. Runs at 00:00, 02:00, 04:00 … 22:00 — twelve times a day.

Handy for moderately heavy jobs — batch imports, reindexing, or reports that don't need to be hourly.

Will you know if a every 2 hours run is skipped?

Knowing when 0 */2 * * * should fire is only half of it. The failure that hurts is the silent one — the box was asleep, the trigger broke, the token expired, and nobody noticed. Cronpulse is a free dead-man's-switch: your job pings a URL each time it runs on this schedule, and if a ping goes missing, we alert you by email, Discord, Slack, or webhook.
