Questions

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

GMT is currently 3 hours ahead of BRT. Add 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 12 * * 1-5 in GMT.

What is the time difference between BRT and GMT?

Brasília Time is UTC-3 and Greenwich Mean Time (UK) is UTC+0 / UTC+1. Right now gMT is currently 3 hours ahead of BRT.

Does daylight saving time affect BRT to GMT cron conversion?

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

What is midnight BRT in GMT cron?

Midnight in BRT (0 0 * * *) is 0 3 * * * in GMT.
