Questions

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

BRT is currently 11 hours behind CST. Subtract 11 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 22 * * 0-4 in BRT.

What is the time difference between CST and BRT?

China Standard Time is UTC+8 and Brasília Time is UTC-3. Right now bRT is currently 11 hours behind CST.

Does daylight saving time affect CST to BRT cron conversion?

Neither CST nor BRT observes daylight saving time, so the 11 hours difference stays the same all year.

What is midnight CST in BRT cron?

Midnight in CST (0 0 * * *) is 0 13 * * * in BRT, on the previous day.
