Questions

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

KST is currently 1 hour behind AEST. Subtract 1 hour 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 8 * * 1-5 in KST.

What is the time difference between AEST and KST?

Brisbane Time (Queensland) is UTC+10 and Korea Standard Time is UTC+9. Right now kST is currently 1 hour behind AEST.

Does daylight saving time affect AEST to KST cron conversion?

Neither AEST nor KST observes daylight saving time, so the 1 hour difference stays the same all year.

What is midnight AEST in KST cron?

Midnight in AEST (0 0 * * *) is 0 23 * * * in KST, on the previous day.
