Convert Azure Functions cron to Google Cloud Scheduler
Azure Functions expressions look similar to Google Cloud Scheduler, but the differences matter. Paste yours below; the result is checked against the original run times.
What changes from Azure Functions to Google Cloud Scheduler
- Google Cloud Scheduler has no seconds field, so a schedule that fires on specific seconds cannot be converted exactly. The seconds value is dropped and flagged.
- Azure Functions requires both day fields to match; Google Cloud Scheduler fires when either does. Schedules that restrict both are flagged.
Worked examples
| Schedule | Azure Functions | Google Cloud Scheduler |
|---|---|---|
| every minute | 0 * * * * * | * * * * * |
| every 5 minutes | 0 */5 * * * * | */5 * * * * |
| every 10 minutes | 0 */10 * * * * | */10 * * * * |
| every 15 minutes | 0 */15 * * * * | */15 * * * * |
| every 30 minutes | 0 */30 * * * * | */30 * * * * |
| every hour | 0 0 * * * * | 0 * * * * |
| every 2 hours | 0 0 */2 * * * | 0 */2 * * * |
| every 3 hours | 0 0 */3 * * * | 0 */3 * * * |
Conversions that come with a warning
- every 10 seconds:
*/10 * * * * *โ* * * * *. Google Cloud Scheduler has no seconds field; the seconds value "*/10" was dropped. - every 30 seconds:
*/30 * * * * *โ* * * * *. Google Cloud Scheduler has no seconds field; the seconds value "*/30" was dropped.
Field layout and time zones
second (0-59), minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-6, 0 = Sunday).
Azure Functions evaluates NCRONTAB in UTC unless the WEBSITE_TIME_ZONE app setting is set; with it, the schedule adjusts for daylight saving. The setting is not supported on Linux Consumption or Flex Consumption plans.
minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-7, 0 and 7 = Sunday).
Cloud Scheduler takes any tz database zone (default UTC) and runs on wall-clock time, so daylight saving can make jobs run or not run unexpectedly. Google recommends UTC to avoid that.

Frequently asked questions
How do I convert a Azure Functions cron expression to Google Cloud Scheduler?
Paste it into the converter above with Azure Functions as the source and Google Cloud Scheduler as the target. For example, 0 * * * * * becomes * * * * *.
Is every Azure Functions expression convertible to Google Cloud Scheduler?
Yes for the common schedules we tested (29 of 29), though unusual expressions with special characters might need manual review.
Does Google Cloud Scheduler run in the same time zone as Azure Functions?
Not necessarily. Conversion changes the syntax, not the time zone. Check where each system evaluates the schedule before you rely on the same clock times.
