Questions

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

JST is currently 1 hour ahead of HKT. Add 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 HKT) becomes 0 10 * * 1-5 in JST.

What is the time difference between HKT and JST?

Hong Kong Time is UTC+8 and Japan Standard Time is UTC+9. Right now jST is currently 1 hour ahead of HKT.

Does daylight saving time affect HKT to JST cron conversion?

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

What is midnight HKT in JST cron?

Midnight in HKT (0 0 * * *) is 0 1 * * * in JST.
