Not as easy as a spreadsheet formula for the purpose.
A spreadsheet is quite an effective tool for finding "what day is the 1st of the month."
It may lack the elegance of other methods; but so what?
The spreadsheet formula will be probably accurate until 2099. Nothing in the problem spec suggests the checks will be issued after that year.
