## 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.
• 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).

• 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.

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

While this table makes it clear how to do the calculations manually, our calculator can do it for you instantly. Try it out and find out how many days are left until your next birthday!
