Questions

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

NZST is currently 4 hours ahead of KST. Add 4 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 13 * * 1-5 in NZST.

What is the time difference between KST and NZST?

Korea Standard Time is UTC+9 and New Zealand Time is UTC+12 / UTC+13. Right now nZST is currently 4 hours ahead of KST.

Does daylight saving time affect KST to NZST cron conversion?

NZST observes daylight saving time, so the difference between KST (UTC+9) and NZST (UTC+12 / UTC+13) changes during the year. Re-check your converted cron after each DST change.

What is midnight KST in NZST cron?

Midnight in KST (0 0 * * *) is 0 4 * * * in NZST.
