Questions

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

HST is currently 23 hours behind NZST. Subtract 23 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 10 * * 0-4 in HST.

What is the time difference between NZST and HST?

New Zealand Time is UTC+12 / UTC+13 and Hawaii Time is UTC-10. Right now hST is currently 23 hours behind NZST.

Does daylight saving time affect NZST to HST cron conversion?

NZST observes daylight saving time, so the difference between NZST (UTC+12 / UTC+13) and HST (UTC-10) changes during the year. Re-check your converted cron after each DST change.

What is midnight NZST in HST cron?

Midnight in NZST (0 0 * * *) is 0 1 * * * in HST, on the previous day.
