Now I want to create a cell with the second argument for the DAYS360 function: the game date. I'll type "Sep 13" into cell B4. Google spreadsheets understand that I am typing a date and automatically convert the text to this format: "9/13/2009."
So far, so good. Now that we have our two arguments, we are ready to use the DAYS360 function. The syntax for DAYS360 is "=DAYS360(date_1, date_2, type)". Because date_1 is located in cell A2 and date_2 is located in cell B4, the function should look like this: "=DAYS360(A2, B4)". (The "type" argument is optional and not necessary here so I'll omit it). I could also have skipped typing "Aug 13" into its own cell and written the function like this: "=DAYS360(A2, "8/13/2009")".
Triumph! Upon hitting return, the function gives me the number of days between now and the Eagles' first regular season game: 36.
