Questions

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

KST is currently 4 hours behind NZST. Subtract 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 NZST) becomes 0 5 * * 1-5 in KST.

What is the time difference between NZST and KST?

New Zealand Time is UTC+12 / UTC+13 and Korea Standard Time is UTC+9. Right now kST is currently 4 hours behind NZST.

Does daylight saving time affect NZST to KST cron conversion?

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

What is midnight NZST in KST cron?

Midnight in NZST (0 0 * * *) is 0 20 * * * in KST, on the previous day.
