## 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.

Interval Values | Description |
---|---|

d | Number of whole days between Start date and End date. |

m | Number of whole months between Start date and End date. |

y | Number of whole years between Start date and End date. |

ym | Number of whole months when subtracting years from the difference of Start date and End date. |

md | Number of whole days when subtracting years and months from the difference of Start date and End date. |

yd | Number of whole days when subtracting years from the difference of Start date and End date. |

## 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.
