Excel Guides

There are a few different ways to calculate the number of days left in the year in Excel. One way is to use the **DATEDIF** function. This function calculates the number of days, months, or years between two dates. To use this function, you need to know the start date and the end date. For our purposes, the start date is January 1st and the end date is December 31st. The DATEDIF function takes three arguments: the start date, the end date, and "d" for days. So, our formula would look like this:

**=DATEDIF(A1,B1,"d")**

Where A1 is the cell containing January 1st and B1 is the cell containing December 31st.

Another way to calculate the number of days left in the year is to use the **DAYS360** function. This function calculates the number of days between two dates based on a 360-day year (12 30-day months). To use this function, you need to know the start date and the end date. For our purposes, again, the start date is January 1st and the end date is December 31st. The DAYS360 function takes four arguments: the start date, the end date, TRUE if you want to use US (NASD) rules for calculating interest, or FALSE if you don't want to use those rules (we don't need to worry about that for our purposes), and 0 if you want to count days from January 0 or 1 if you want to count days from February 0. So, our formula would look like this:

**=DAYS360(A1,B1,FALSE,0)**

Where A1 is the cell containing January 1st and B1 is the cell containing December 31st.

You can also use a simple subtraction formula to calculate the number of days left in the year. To do this, you need to know today's date and then subtract it from December 31st. So, our formula would look like this:

**=B1-TODAY()**

Where B1 is the cell containing December 31st.
