To determine how many days are left until the Christmas holiday, one should first determine the current date. Christmas takes place on the 25th day of December. Considering the number of days in each month, count out the days remaining until December 25th.

An example is the 17th of November. There are 30 days in the month of November. With the date being the 17th, there are 12 full days left in the month. Since the holiday falls on the 25th of December, one should add 12 plus 24 days to reach the 25th day of December. There are multiple options online offering Christmas countdowns.

**Look up the current date and count to the nearest 25th**Begin by knowing the current date. Count how many days are between that date and the next 25th of a month. For example, if today is Sept. 19, there are 6 days to Sept. 25.

**Determine how many days are in the months between the next 25th and Christmas**If the closest 25th is Sept. 25, there are three months until Christmas, but those three months equal 91 days, because September and November each have thirty days.

**Add together the days**Add the number of days between the current date and the next 25th of the month to the number of days in the months leading to Christmas. For example, the days until Christmas from Sept. 19 is 97.
