Questions

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

AWST is currently 1 hour behind JST. Subtract 1 hour 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 8 * * 1-5 in AWST.

What is the time difference between JST and AWST?

Japan Standard Time is UTC+9 and Australian Western Time is UTC+8. Right now aWST is currently 1 hour behind JST.

Does daylight saving time affect JST to AWST cron conversion?

Neither JST nor AWST observes daylight saving time, so the 1 hour difference stays the same all year.

What is midnight JST in AWST cron?

Midnight in JST (0 0 * * *) is 0 23 * * * in AWST, on the previous day.
