All Timezone Conversions

Cron UTC to GMT

Convert cron job schedules from UTC to GMT timezone.

Timezone Offset

+0 hours

UTC (UTC+0) → GMT (UTC+0)

Conversion Examples

To run a job at a specific UTC time, use the GMT expression below:

Target time (UTC) Cron in GMT Equivalent GMT time
Midnight UTC0 0 * * *Midnight
9 AM UTC0 9 * * *9 AM
Noon UTC0 12 * * *Noon
5 PM UTC0 17 * * *5 PM

How to Use

If your server runs in GMT but you want jobs to execute at UTC times:

  1. Take your desired UTC hour
  2. Add 0 hours
  3. If result is negative, add 24 (job runs previous day)
  4. If result is 24 or more, subtract 24 (job runs next day)

For complex schedules, use our Timezone Converter Tool to see exact run times in both timezones.

Important Notes

  • Standard cron has no timezone support - it uses the server's local time
  • Day boundaries: When converting crosses midnight, the day also changes
  • DST: Consider daylight saving time - offsets may change by 1 hour seasonally
  • Kubernetes & cloud platforms: Many support explicit timezone configuration
