Questions

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

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

What is the time difference between GMT and BRT?

Greenwich Mean Time (UK) is UTC+0 / UTC+1 and Brasília Time is UTC-3. Right now bRT is currently 3 hours behind GMT.

Does daylight saving time affect GMT to BRT cron conversion?

GMT observes daylight saving time, so the difference between GMT (UTC+0 / UTC+1) and BRT (UTC-3) changes during the year. Re-check your converted cron after each DST change.

What is midnight GMT in BRT cron?

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