Questions

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

KST is currently 2 hours behind AEST. Subtract 2 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 AEST) becomes 0 7 * * 1-5 in KST.

What is the time difference between AEST and KST?

Australian Eastern Time is UTC+10 / UTC+11 and Korea Standard Time is UTC+9. Right now kST is currently 2 hours behind AEST.

Does daylight saving time affect AEST to KST cron conversion?

AEST observes daylight saving time, so the difference between AEST (UTC+10 / UTC+11) and KST (UTC+9) changes during the year. Re-check your converted cron after each DST change.

What is midnight AEST in KST cron?

Midnight in AEST (0 0 * * *) is 0 22 * * * in KST, on the previous day.
