Having trouble with date calculations in LibreOffice Calc? In this guide, you will learn how to calculate the types of date difference in LibreOffice Calc.

## Calculate Date Difference

Its always better to use a function to calculate the date difference. `DATEDIF` the function does just that. This function returns the number of whole days, months, years between two given start and end dates.

#### Syntax

`=DATEDIF(Start date; End date; Interval)`
• Start date and End date are the date range for your calculation.
• Interval is a string and accepted values are below.

## Examples

#### Number of days between two dates

If you want to calculate the number of days between two dates, use the `DATEDIF` function with interval `"d"`.

`=DATEDIF(A2,B2,"d")`

#### Number of months between two dates

In the above example, replace the interval with `m` to find out the number of months between two dates.

`=DATEDIF(A2,B2,"m")`

#### Number of years between two dates

Likewise, use the interval value `y` to calculate the number of years between two dates.

`=DATEDIF(A2,B2,"y")`

#### Number of months ignoring years

If you want to calculate the number of months between two dates ignoring the years, then use `ym` in the interval parameter.

#### Number of days ignoring months

Similarly to calculate the number of days between two dates ignoring the months, then use `ym` in the interval parameter.

#### Number of days ignoring years

Likewise, if you want to calculate the number of days between two dates ignoring the years, then use `yd` in the interval parameter.

#### Age calculation using birthday

You can also calculate age using the birthday of a person using the below formula by calculating `DATEDIF` between birthday and today’s date (via `TODAY()` function).

## Usage Notes

If you do a `DATEDIF` between two dates where your end date is less than your start date then you would get `Err:502`. So, in those cases, you can use `=MONTH() `or `DAY() `function and do subtraction between them.
