Questions

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

GMT is currently 8 hours behind HKT. Subtract 8 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 HKT) becomes 0 1 * * 1-5 in GMT.

What is the time difference between HKT and GMT?

Hong Kong Time is UTC+8 and Greenwich Mean Time (UK) is UTC+0 / UTC+1. Right now gMT is currently 8 hours behind HKT.

Does daylight saving time affect HKT to GMT cron conversion?

GMT observes daylight saving time, so the difference between HKT (UTC+8) and GMT (UTC+0 / UTC+1) changes during the year. Re-check your converted cron after each DST change.

What is midnight HKT in GMT cron?

Midnight in HKT (0 0 * * *) is 0 16 * * * in GMT, on the previous day.
