**In this tutorial, we will show you how to calculate the next birthday from today in Excel. With a few simple formulas, you can easily create a spreadsheet that calculates the number of days until each person’s next birthday, so you’ll never forget to send a birthday wish again. **

**Calculating the next date of one’s birthday. **As an example, we have the names of the employees in column A and their corresponding birthdays in column B. We want to calculate their next birthday from today’s date. To do this, we will use the DATE and DATEDIF formulas and mathematical operators. Here’s a step-by-step guide:

- First, we add today’s date in column C. We then input the formula “=TODAY()” without the quotes. This will display the current date in that cell. Copy-paste the formula to the rest of the C column.
- In column D, input the formula “=DATE(YEAR(B2)+DATEDIF(B2,C2,”y”)+1,MONTH(B2),DAY(B2))” without the quotes.

This will calculate the next birthday of the employee by taking his birth year from the cell in column B and adding the difference between his birth year and the current year plus 1, the month from the cell in column B, and the day from the cell in column B.

**Calculating the number of days until one’s birthday **In the same example, we want to calculate how many days remain until their birthday. To do this, we will use the DATEDIF function. First, in column E, input the formula “=DATEDIF(C2,D2,”d”)” without the quotes and then press Enter. This will calculate the number of years between today’s date and the employee’s next birthday.

## Conclusion

Using a combination of Excel formulas such as DATE, DATEDIF, and mathematical operators, it is possible to easily calculate the next birthday of a person from today’s date. This can be a useful tool for remembering to send birthday wishes or for keeping track of important dates in your business or personal life. Now that you know how to calculate the next birthday from today in Excel, you can put this knowledge to use and make your life easier.
