Questions

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

GMT is currently 6 hours ahead of CST. Add 6 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 15 * * 1-5 in GMT.

What is the time difference between CST and GMT?

Central Time is UTC-6 / UTC-5 and Greenwich Mean Time (UK) is UTC+0 / UTC+1. Right now gMT is currently 6 hours ahead of CST.

Does daylight saving time affect CST to GMT cron conversion?

CST and GMT observe daylight saving time, so the difference between CST (UTC-6 / UTC-5) and GMT (UTC+0 / UTC+1) changes during the year. Re-check your converted cron after each DST change.

What is midnight CST in GMT cron?

Midnight in CST (0 0 * * *) is 0 6 * * * in GMT.
