## How to Count the Days Until Halloween

Every year, Halloween falls on **October 31st** in the United States.

You can count the days until Halloween in a few different ways, but the easiest is to use our Halloween countdown calculator.

If the current month is October, then you can find how many days are left using subtraction. Subtract the current day from 31, since Halloween falls on October 31st.

days until Halloween = 31 – current day

You can also find how many days there are until Halloween by adding the days left in the current month to the days in each month until November, then the days in the month of November before Halloween (30).

days until Halloween = days left in current month + days in next month + … + 30 days in October before Halloween

You can use the same method to find how many days until New Year’s, Christmas, July 4th, or any other significant date.

**For instance,** if it’s currently August 29th, then you can find the days until Halloween on October 31st like this:

days until Halloween = 2 + 30 + 30

days until Halloween = 62 days

In this example, there are 2 days remaining in August, 30 days in September, and 30 days in October before Halloween. Thus, there are 62 days left.

You can do this same calculation using a time duration calculator.
