Questions

How do I convert a cron expression from HST to CST?

CST is currently 4 hours ahead of HST. Add 4 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 HST) becomes 0 13 * * 1-5 in CST.

What is the time difference between HST and CST?

Hawaii Time is UTC-10 and Central Time is UTC-6 / UTC-5. Right now cST is currently 4 hours ahead of HST.

Does daylight saving time affect HST to CST cron conversion?

CST observes daylight saving time, so the difference between HST (UTC-10) and CST (UTC-6 / UTC-5) changes during the year. Re-check your converted cron after each DST change.

What is midnight HST in CST cron?

Midnight in HST (0 0 * * *) is 0 4 * * * in CST.
