Create a 12 month formatted calendar on a new tab in Excel with the current day highlighted. This macro creates a nicely formatted 12 month calendar where all days in every month are listed and in date format. This means that you can immediately perform date related functions and formulas off of the dates created from this macro and calendar.
This macro saves you a lot of time if you need to have a calendar display in Excel. This macro is also very easy to change in terms of formatting and this is good if you want to change month heading colors or cell background colors etc.
