# Age (DateTimeOffset)
| **Name** | ***Age With Offset*** |
| ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Syntax | Age (DateTimeWithOffset start, DateTimeWithOffset end, Integer interval) |
| Purpose | To compute the difference between two specified date time offset values, based on interval type (year, Month etc.) provided in integer form. |
| Description | Compute the difference between two dates and return age in a specified interval. Valid values for interval: 1=Year, 2=Month, 3=Week, 4=Day, 5=Hour, 6=Minute, or 7=Second |
| Return Type | Int64 |
| Parameters |
start \[System.DateTimeOffset]
end \[System.DateTimeOffset]
interval \[System.Int32]
|
**Example**
In this example, we will pass date time offset values, and an integer value (indicating a specific interval) to the function transformation object using a *Variables* object.
Where,
*start* = 01/03/2022
*end* = 06/06/2022
*interval (3=week)* = 3
In the output window, you can see that the provided interval value, indicating weeks, has been used to compute the age between the two specified date time offset values.
