Questions

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

NZST is currently 17 hours ahead of AST. Add 17 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 AST) becomes 0 2 * * 2-6 in NZST.

What is the time difference between AST and NZST?

Atlantic Time is UTC-4 / UTC-3 and New Zealand Time is UTC+12 / UTC+13. Right now nZST is currently 17 hours ahead of AST.

Does daylight saving time affect AST to NZST cron conversion?

AST and NZST observe daylight saving time, so the difference between AST (UTC-4 / UTC-3) and NZST (UTC+12 / UTC+13) changes during the year. Re-check your converted cron after each DST change.

What is midnight AST in NZST cron?

Midnight in AST (0 0 * * *) is 0 17 * * * in NZST.
