Questions

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

NZST is currently 4 hours ahead of JST. 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 JST) becomes 0 13 * * 1-5 in NZST.

What is the time difference between JST and NZST?

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

Does daylight saving time affect JST to NZST cron conversion?

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

What is midnight JST in NZST cron?

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