SSRS DatePart Function

The SSRS DatePart function is a Date and Time function that will help you extract individual date parts (specified component) from the given date fields and return the integer value. For instance, extract years, months, hours, days, etc., from the order date for analysis purposes. The syntax of the SSRS DatePart function to return the required date or time part from the given date is as shown below.

=DatePart("m", Fields!HireDate.Value)
=DatePart(DateInterval.Day, Fields!OrderDate.Value, FirstDayOfWeek.System, FirstWeekOfYear.System )

To demonstrate the SSRS DatePart function, we use the Employee table below, which has 15 records. The image shows the records in the Table report.

" Month = " & DatePart("m", Fields!HireDate.Value) &
" Day = " & DatePart("d",Fields!HireDate.Value) &
" Quarter = " & DatePart("q", Fields!HireDate.Value) &
" Week = " & DatePart("ww", Fields!HireDate.Value) &

" Hour = " & DatePart("h", Fields!HireDate.Value) &
