--http-method=POSTThe Google Cloud Scheduler fields, in order: minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-7, 0 and 7 = Sunday).
Things to watch out for in Google Cloud Scheduler
- If both day-of-month and day-of-week are set, the job runs when either matches (an inclusive OR), unless one of them is *.
- Pick the time zone explicitly (the default is UTC). Cloud Scheduler runs on wall-clock time, so a local zone can make jobs run or skip around daylight saving changes.
- 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.
The common mistake with this schedule
The 15th can be a weekend. Cron cannot shift to the next business day on its own; check in the job, or use Quartz 15W for the nearest weekday.
