What is the best way to structure the schedule for this scenario? I do not see that the “preset” schedule allows for monthly. In the cron expression, a “day of the month” can be set - however - will IO know to run the flow on the 28th or 30th if it is not a 31 day month? ---

Hi @Jay_Juen This one is also great for feedback to have the cron settings be a bit more improved in Celigo. I’m afraid you now need a small workaround for this case: In the cron job, select the day of the month and choose 28, 29, 30, and 31. Then, in the flow itself, use a script to check whether it’s actually the last day of the month, and only proceed if that condition is met. Also, check @tylerlamparter last comment here — it might be helpful: 👉 [https://connective.celigo.com/t/set-flow-schedule-to-every-2-weeks/4544/7](https://connective.celigo.com/t/set-flow-schedule-to-every-2-weeks/4544/7)
