I saw an Excel spreadsheet once that had a date column that would span a couple of month down and that would be the end of the spreadsheet, but every day you open and use it, that date at the bottom would add and the date at the top would disappear, so basically you have an "infinite" spreadsheet that automatically moves forward with time as you use it every day. I struggle finding the solution for this on the net, any input would be greatly appreciated.

Have a great day everyone!
