I have a spreadsheet where I track my expenses. Each month has it's own tab (e.g., Jan, Feb, Mar...).
Within the month tab, I break the month down into four weeks and track my spending weekly.
I have written a script to create a new month tab, but I'm not sure how to set those weekly date ranges since months have different numbers of days (i.e., 28, 30, 31).
How would I go about setting the following items regardless of the month: - first day of first week of month - last day of first week of month - first day of second week of month - last day of second week of month - first day of third week of month - last day of third week of month - first day of fourth week of month
