I have a calendar setup month to month on one sheet. So like C5 is 1-1-13 and D5 is 1-2-13 then B6 starts the next week (Sorry I couldn't get the table insert to work for me here). I also have the display only show the day of the month. Then on sheet 2 I have a list of holiday dates, is there a way I can have a vlookup in sheet 1 and if a date matches on sheet 2 it has a different background?
