A simple manual (button) flow. For a given date (mm/dd/yyyy), the flow will calculate the number of days that specific month (mm) has. It also gives you the end of the month. This fills a gap in the Flow expressions as there is a Start of the month expression but no End of the month expression.
Note: Yes, Flow takes care of leap year calculation when calculating the days (for Feb).
Thank you @tbandama. Love to hear more on how this flow solved your business problem/requirement.
@svarukala as a supplement to your great flow I created a simple implementation of "Send an e-mail notification the last working day of the month"
You may find it useful.
Good work @Michal. For me calendar/dates is a complicated topic, similar to regex. Happy to see more flows around this topic.
