In practice, we often need to calculate the difference of years, months, weeks or days between 2 separate dates. And like many other calculations, **Excel functions** can help you **calculate the time difference quickly and accurately**. Let’s see how to do it.

## Case 1: Calculate the Difference of Years

Formula: **=DATEDIF(A2,B2,”y”)**

**A2**, **B2** corresponds to the cells with the 2 different dates.

**“y”** refers to years.

**[Enter]**to work it out.

## Case 2: Calculate the Difference of Months

Formula: **=DATEDIF(A2,B2,”m”)**

**A2**, **B2** corresponds to the cells with the 2 different dates.

**“m”** refers to months.

## Case 3: Calculate the Difference of Days

Formula: **=DATEDIF(A2,B2,”d”)**

**A2**, **B2** corresponds to the cells with the 2 different dates.

**“d”** refers to days.

Enter the formula in C2 and use fill handle to apply it to multiple cells.

## Case 4: Calculate the Difference of Weeks

Formula: **=DATEDIF(A2,B2,”d”)/7**

**A2**, **B2** corresponds to the cells with the 2 different dates.

**“d”** refers to days.

The difference of weeks is basically dividing the difference of days by 7.

If you want to separately calculate the difference of numbers in years, months and days, you can use these formulas:

Years: **=DATEDIF(A2,B2,”y”)**

Months: **=DATEDIF(A2,B2,”ym”)**

Days: =**DATEDIF(A2,B2,”md”)**

Enter these formulas in 3 cells and press **[Enter]**, you can get the result of the difference of years, months and days separately.
