Frequently Asked Questions
How is Azure Functions different from standard Linux cron?
Azure Functions differs from Linux cron in field count, day-of-week numbering, or supported special characters — see the Quick Reference table above for the exact differences.
Can I convert a Linux cron expression to Azure Functions automatically?
Yes — paste it into the multi-platform Cron tool above (or on the main Cron Editor page) and switch to the Azure Functions tab to get the equivalent expression instantly.
Does Azure Functions support L, W, or # ?
No. Azure Functions doesn't support L or # — see the workaround pattern in the tool above for equivalent behavior using a day range and an in-script check.
Does Azure Functions run on my local timezone or UTC?
Azure Functions evaluates schedules in whatever timezone you configure (or the system/server timezone if none is set) — it isn't fixed to UTC.
