Cron Job Every 20 Minutes

A 20-minute interval provides 3 executions per hour at minutes 0, 20, and 40. This is useful when 15 minutes is too frequent but 30 minutes is too sparse.

Frequently Asked Questions

The cron expression for every 20 minutes is */20 * * * *. This runs at minutes 0, 20, and 40 of every hour - three times per hour or 72 times per day.
Use 20-minute intervals when you need regular updates but 15 minutes would create too much load, and 30 minutes would be too infrequent. It's a good middle ground for API polling with rate limits.
