I need to send monthly email reminders on the last business day of the month. This seems like something a lot of companies would need to do. I currently have a team member manually calculating how many days are in between months in order to send these on the right date (but there is still not way for me to verify that the email will send on the date I want it to. It should not be this difficult. From a programming perspective - it seems like you’d just need to create an annual calendar formula for this to work. I think this would be a great hack day project.
