Cron Every Monday and Wednesday

The cron expression 0 0 * * 1,3 triggers at midnight every Monday and Wednesday. The comma-separated list 1,3 in the day-of-week field means "Monday and Wednesday."

This twice-weekly schedule creates an even split of the work week — roughly 2 days between each run (Mon→Wed is 2 days, Wed→Mon is 5 days including the weekend). It's useful for tasks that need more than weekly attention but less than daily: semi-weekly data syncs, twice-weekly report generation, and bi-weekly cleanup jobs.

To run at a specific time instead of midnight, change the hour and minute fields: 0 9 * * 1,3 runs at 9 AM on Monday and Wednesday. You can also adjust the days — 0 0 * * 2,4 targets Tuesday and Thursday instead.
