monthly - The flow will run monthly on the same day of the month. For example, if the start date is the 11 of March, the flow will always run on the 11th of each following month until the end date or if it is not chosen, indefinitely. Each case: If you schedule it on the 30 of June, the flow will always run on the 30th of each month, and in the case of February, having usually only 28 days, the flow will run on the last day of February. Meaning, if a month has fewer days than the chosen day, the flow will run on the last day of the month. We found that this serves most business cases and hopefully also yours.
