Create a list of sequential dates
You can quickly create a list of dates, in sequential order, by using the Fill Handle or the Fill command.
Use the Fill Handle
Select the cell that contains the first date. Drag the fill handle across the adjacent cells that you want to fill with sequential dates.
Select the fill handle at the lower-right corner of the cell, hold down, and drag to fill the rest of the series. Fill handles can be dragged up, down, or across a spreadsheet.
Use the Fill command
Select the cell with the first date. Then select the range of cells you want to fill.
Select Home > Editing > Fill > Series > Date unit. Select the unit you want to use.
Tip: You can sort dates much like any other data. By default, dates are sorted from the earliest date to the latest date.
