Workers - Cron triggers are now supported in Python Workers

You can now create Python Workers which are executed via a cron trigger. This is similar to how it's done in JavaScript Workers, simply define a scheduled event listener in your Worker: from workers import handler @ handler async def on_scheduled ( event , env , ctx ): print ( "cron processed" ) Define a cron trigger configuration in your Wrangler configuration file: wrangler.jsonc { " triggers " : { // Schedule cron triggers: // - At every 3rd minute // - At 15:00 (UTC) on first day of the month // - At 23:59 (UTC) on the last weekday of the month " crons " : [ "*/3 * * * *" , "0 15 1 * *" , "59 23 LW * *" ] } } wrangler.toml [ triggers ] crons = [ "*/3 * * * *" , "0 15 1 * *" , "59 23 LW * *" ] Then test your new handler by using Wrangler with the --test-scheduled flag and making a request to /cdn-cgi/handler/scheduled?cron=*+*+*+*+* : npx wrangler dev --test-scheduled curl " Consult the Workers Cron Triggers page for full details on cron triggers in Workers.
