Questions

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

SAST is currently 8 hours ahead of CST. Add 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 CST) becomes 0 17 * * 1-5 in SAST.

What is the time difference between CST and SAST?

Central Time is UTC-6 / UTC-5 and South Africa Standard Time is UTC+2. Right now sAST is currently 8 hours ahead of CST.

Does daylight saving time affect CST to SAST cron conversion?

CST observes daylight saving time, so the difference between CST (UTC-6 / UTC-5) and SAST (UTC+2) changes during the year. Re-check your converted cron after each DST change.

What is midnight CST in SAST cron?

Midnight in CST (0 0 * * *) is 0 8 * * * in SAST.
