Questions

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

HKT is currently 1 hour behind KST. 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 KST) becomes 0 8 * * 1-5 in HKT.

What is the time difference between KST and HKT?

Korea Standard Time is UTC+9 and Hong Kong Time is UTC+8. Right now hKT is currently 1 hour behind KST.

Does daylight saving time affect KST to HKT cron conversion?

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

What is midnight KST in HKT cron?

Midnight in KST (0 0 * * *) is 0 23 * * * in HKT, on the previous day.
