How cron expressions work
A cron expression has five fields: minute (0-59), hour (0-23), day of month (1-31), month (1-12) and day of week (0-6, Sunday is 0). A * means every value, */5 means every 5 units, 1,15 lists values and 1-5 is a range.
For example, 0 9 * * 1 runs at minute 0 of hour 9 on Mondays. Cron is used by Linux servers, CI systems, Kubernetes and most job schedulers.
