Questions

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

CST is currently 3 hours behind BRT. Subtract 3 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 BRT) becomes 0 6 * * 1-5 in CST.

What is the time difference between BRT and CST?

Brasília Time is UTC-3 and Central Time is UTC-6 / UTC-5. Right now cST is currently 3 hours behind BRT.

Does daylight saving time affect BRT to CST cron conversion?

CST observes daylight saving time, so the difference between BRT (UTC-3) and CST (UTC-6 / UTC-5) changes during the year. Re-check your converted cron after each DST change.

What is midnight BRT in CST cron?

Midnight in BRT (0 0 * * *) is 0 21 * * * in CST, on the previous day.
