Questions

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

CST is currently 8 hours behind SAST. 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 SAST) becomes 0 1 * * 1-5 in CST.

What is the time difference between SAST and CST?

South Africa Standard Time is UTC+2 and Central Time is UTC-6 / UTC-5. Right now cST is currently 8 hours behind SAST.

Does daylight saving time affect SAST to CST cron conversion?

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

What is midnight SAST in CST cron?

Midnight in SAST (0 0 * * *) is 0 16 * * * in CST, on the previous day.
