Access: DatePart Function
In Access, the DatePart function returns a specified part of a given date.
The syntax for the DatePart function is:
DatePart ( interval, date, [firstdayofweek], [firstweekofyear])
interval is the interval of time that you wish to return. This parameter can be any one of the following valid interval values:
Interval Explanation yyyy Year q Quarter m Month y Day of year d Day w Weekday ww Week h Hour n Minute s Second
date is the date value that you wish to evaluate.
firstdayofweek is optional. It is a constant that specifies the first day of the week. If this parameter is omitted, Access assumes that Sunday is the first day of the week. This parameter can be one of the following values:
Constant Value Explanation vbUseSystem 0 Use the NLS API setting vbSunday 1 Sunday (default) vbMonday 2 Monday vbTuesday 3 Tuesday vbWednesday 4 Wednesday vbThursday 5 Thursday vbFriday 6 Friday vbSaturday 7 Saturday
firstweekofyear is optional. It is a constant that specifies the first week of the year. If this parameter is omitted, Access assumes that the week containing Jan 1st is the first week of the year. This parameter can be one of the following values:
Constant Value Explanation vbUseSystem 0 Use the NSL API setting vbFirstJan1 1 Use the first week that includes Jan 1st (default) vbFirstFourDays 2 Use the first week in the year that has at least 4 days vbFirstFullWeek 3 Use the first full week of the year
For example:
DatePart ("yyyy", #15/10/1998#) would return 1998 DatePart ("m", #15/10/2003#) would return 10 DatePart ("d", #15/10/2003#) would return 15
VBA Code
The DatePart function can be used in VBA code. For example:
Dim LValue As Integer
LValue = DatePart ("d", #15/10/2003#)
In this example, the variable called LValue would now contain the value of 15.
SQL/Queries
You can also use the DatePart function in a query.
