Convert Azure Functions cron to Spring
Azure Functions expressions look similar to Spring, but the differences matter. Paste yours below; the result is checked against the original run times.
What changes from Azure Functions to Spring
- Azure Functions and Spring use the same five-field layout and weekday numbering, so most expressions convert unchanged.
Worked examples
| Schedule | Azure Functions | Spring |

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.
second (0-59), minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-7, 0 and 7 = Sunday).
Spring evaluates in the server time zone by default. Add zone = "UTC" (or any ZoneId) to @Scheduled to make it explicit.

Frequently asked questions
How do I convert a Azure Functions cron expression to Spring?
Paste it into the converter above with Azure Functions as the source and Spring as the target. For example, 0 * * * * * becomes 0 * * * * *.
Is every Azure Functions expression convertible to Spring?
Yes for the common schedules we tested (29 of 29), though unusual expressions with special characters might need manual review.
Does Spring 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.
