Questions

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

KST 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 KST.

What is the time difference between EST and KST?

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

Does daylight saving time affect EST to KST cron conversion?

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

What is midnight EST in KST cron?

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