Questions

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

AKST is currently 18 hours behind KST. Subtract 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 KST) becomes 0 15 * * 0-4 in AKST.

What is the time difference between KST and AKST?

Korea Standard Time is UTC+9 and Alaska Time is UTC-9 / UTC-8. Right now aKST is currently 18 hours behind KST.

Does daylight saving time affect KST to AKST cron conversion?

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