Questions

How do I convert a cron expression from CST to JST?

JST is currently 15 hours ahead of CST. Add 15 hours to the hour field, and shift the day-of-week if the time crosses midnight. For example, 0 9 * * 1-5 (weekdays at 09:00 CST) becomes 0 0 * * 2-6 in JST.

What is the time difference between CST and JST?

Central Time is UTC-6 / UTC-5 and Japan Standard Time is UTC+9. Right now jST is currently 15 hours ahead of CST.

Does daylight saving time affect CST to JST cron conversion?

CST observes daylight saving time, so the difference between CST (UTC-6 / UTC-5) and JST (UTC+9) changes during the year. Re-check your converted cron after each DST change.

What is midnight CST in JST cron?

Midnight in CST (0 0 * * *) is 0 15 * * * in JST.
