Questions

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

JST is currently 14 hours ahead of EST. Add 14 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 EST) becomes 0 23 * * 1-5 in JST.

What is the time difference between EST and JST?

Eastern Time is UTC-5 / UTC-4 and Japan Standard Time is UTC+9. Right now jST is currently 14 hours ahead of EST.

Does daylight saving time affect EST to JST cron conversion?

EST observes daylight saving time, so the difference between EST (UTC-5 / UTC-4) and JST (UTC+9) changes during the year. Re-check your converted cron after each DST change.

What is midnight EST in JST cron?

Midnight in EST (0 0 * * *) is 0 14 * * * in JST.
