Questions

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

KST is currently 18 hours ahead of AKST. Add 18 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 AKST) becomes 0 3 * * 2-6 in KST.

What is the time difference between AKST and KST?

Alaska Time is UTC-9 / UTC-8 and Korea Standard Time is UTC+9. Right now kST is currently 18 hours ahead of AKST.

Does daylight saving time affect AKST to KST cron conversion?

AKST observes daylight saving time, so the difference between AKST (UTC-9 / UTC-8) and KST (UTC+9) changes during the year. Re-check your converted cron after each DST change.

What is midnight AKST in KST cron?

Midnight in AKST (0 0 * * *) is 0 18 * * * in KST.
