Create a Calendar Table based on Start and End Date Inputs

If you're into building data models and your tables include dates, a good thing to have is a separate calendar table. You may want to create a calendar table that has the date, month name, year day name, etc. This gives you ways to slice and dice the data for further analysis and also a way to uniformly reference your other tables to one calendar table. It's fairly easy to create a list of dates in Excel by having a start date and incrementing by one day, but that is static. You'll always need to update it when new data comes in. The preferable way to do this is to automate it and that's when Power Query comes into play.
