How to calculate the number of days left in the year
Calculating the number of days left in the year is a pretty simple task. To do this, follow these steps:
-
Find out whether it is a leap year or not. For this exercise, let's assume you are calculating for a non-leap year.
-
Calculate what numbered day of the year it is. We do this by finding the total number of days in all the whole months and then adding the number of days in the current month.
-
So, if the date is the 13th of March, find the total number of days in January and February:
31 + 28 = 59
-
Find the total number of extra days in March and add them to the total above:
59 + 13 = 72
-
-
Subtract the answer above from the total number of days in the year:
365 - 72 = 293
That's it. You just calculated the number of days left in the year.
