Run a cron job every day at midnight
“At 00:00.”
The single most common cron expression in production: minute 0 of hour 0, once per day. Midnight marks the natural boundary for 'yesterday is complete' processing — but it is also when everyone else's jobs run, and in DST zones the 00:xx hour is safe while 02:xx is not.

Field by field
| Field | Value | Meaning |
|---|---|---|
| Minute | 0 | exactly 0 |
| Hour | 0 | exactly 0 |
| Day of month | * | every value |
| Month | * | every value |
| Day of week | * | every value |
Typical uses
- Daily database backups and exports
- Closing out yesterday's metrics and reports
- Rotating logs and pruning old data
Worth knowing: Midnight in the scheduler's timezone, not yours — a UTC server runs this at 07:00 Bangkok time. Log `date` at job start once to confirm.
