Example
Remarks
Use the DatePart function to evaluate a date and return a specific interval of time. For example, you might use DatePart to calculate the day of the week or the current hour.
The firstdayofweek argument affects calculations that use the "w" and "ww" interval symbols.
If date is a date literal, the specified year becomes a permanent part of that date. However, if date is enclosed in double quotation marks (" "), and you omit the year, the current year is inserted in your code each time the date expression is evaluated. This makes it possible to write code that can be used in different years.
Note
For date, if the Calendar property setting is Gregorian, the supplied date must be Gregorian. If the calendar is Hijri, the supplied date must be Hijri.
The returned date part is in the time period units of the current Arabic calendar. For example, if the current calendar is Hijri and the date part to be returned is the year, the year value is a Hijri year.
