Other Ways to Determine Days Until Your Next Birthday
1. The Calendar Method
You can always use a regular calendar to count the days. Here’s how:
- Find today’s date on the calendar.
- Mark your birthday.
- Count the days in between
2. Manual math
Step 1. Find the Difference Between Today’s Date and Your Birthday
First, you need to find the difference between today’s date and your birthday’s date (day of the month).
Step 2. If Your Birthday Has Already Passed This Year
- Figure out how many days are left in the current month. Look at today’s date and see how many days are left until the end of the month.
- Add the number of days in each month between the current month and your birthday month. Count the days for each full month until you reach your birthday month.
- Finally, add the day of your birthday month
Let’s break it down with an example:
Scenario | Example Dates | Calculation Steps | Total Days |
---|---|---|---|
Birthday has already passed this year | Today’s Date: June 12 Birthday: October 15 |
Days left in June: 30 days – 12 (today’s date) = 18 days | 18 |
Days in July: 31 days | 31 | ||
Days in August: 31 days | 31 | ||
Days in September: 30 days | 30 | ||
Days in October before birthday: 15 days | 15 | ||
Total | 125 | ||
Birthday falls in the current month | Today’s Date: June 12 Birthday: June 25 |
Days between today’s date and birthday: 25 (birthday) – 12 (today) | 13 |
