The following functions isolate the date portion and time portion, respectively, of a Date/Time value:

 

Function Description

DateValue Returns the date portion of a Date/Time value, with the time portion "zeroed out". (Note: When the time portion of a date/time variable is "zeroed out", the time would be interpreted as 12:00 AM.)

 

Example:

 

Dim dtmTest As Date

dtmTest = DateValue(Now)

 

At this point, the date portion of dtmTest is 8/31/2001, with a time portion of 0 (12:00 AM midnight).

 

TimeValue Returns the time portion of a Date/Time value, with the date portion "zeroed out". (Note: When a date/time variable is "zeroed out", the date will actually be interpreted as December 30, 1899.)

 

Example:

 

Dim dtmTest As Date

dtmTest = TimeValue(Now)

 

At this point, the time portion of dtmTest is 9:15:20 PM, with a date portion of 0 (12/30/1899).

 

 

The following functions are used to isolate a particular part of a date:

 

Function Description

Weekday Returns a number from 1 to 7 indicating the day of the week for a given date, where 1 is Sunday and 7 is Saturday.

 

Example:

intDOW = Weekday(Now) ' intDOW = 6

 

Note:

When necessary to refer to a day of the week in code, VB has a

set of built-in constants that can be used instead of the hard-coded values 1 thru 7:

Constant Value

vbSunday 1

vbMonday 2

vbTuesday 3

vbWednesday 4

vbThursday 5

vbFriday 6

vbSaturday 7

 

 

Function Description

WeekdayName Returns a string containing the weekday name ("Sunday" thru "Saturday"), given a numeric argument with the value 1 through 7.

 

Example:

strDOW = WeekdayName(6) ' strDOW = "Friday"

 

The WeekdayName function takes an optional, second argument (Boolean) indicating whether or not to abbreviate the weekday name. By default, the second argument is False, meaning do not abbreviate and return the full name. If True, the first three letters of the weekday name will be returned:

 

Example:

strDOW = WeekdayName(6, True) ' strDOW = "Fri"

 

You can nest the Weekday function within the WeekdayName function to get the weekday name for a given date:

 

Example:

strDOW = WeekdayName(Weekday(Now)) ' strDOW = "Friday"

Month Returns a number from 1 to 12 indicating the month portion of a given date.

 

Example:

intMonth = Month(Now) ' intMonth = 8

 

MonthName Returns a string containing the month name ("January" thru "December"), given a numeric argument with the value 1 through 12.

 

Example:

strMoName = MonthName(8) ' strMoName = "August"

 

The MonthName function takes an optional, second argument (Boolean) indicating whether or not to abbreviate the month name. By default, the second argument is False, meaning do not abbreviate and return the full name. If True, the first three

letters of the month name will be returned:

 

Example:

strMoName = MonthName(8, True) ' strMoName = "Aug"

 

You can nest the Month function within the MonthName function to get the month name for a given date:

 

Example:

strMoName = MonthName(Month(Now)) ' strMoName = "August"

 

Day Returns a number from 1 to 31 indicating the day portion of a given date.

 

Example:

intDay = Day(Now) ' intDay = 31

 

Year Returns a number from 100 to 9999 indicating the year portion of a given date.

 

Example:

intYear = Year(Now) ' intYear = 2001

 

 

The following functions are used to isolate a particular part of a time:

 

Function Description

Hour Returns an integer specifying a whole number between 0 and 23 representing the hour of the day.

 

Example:

intHour = Hour(Now) ' intHour = 21 (for 9 PM)

 

Minute Returns an integer specifying a whole number between 0 and 59 representing the minute of the hour.

 

Example:

intMinute = Minute(Now) ' intMinute = 15

 

Second Returns an integer specifying a whole number between 0 and 59 representing the second of the minute.

 

Example:

intSecond = Second(Now) ' intSecond = 20

 

 

To demonstrate the date functions shown thus far, set up a "Try It" project, and place the following code in the cmdTryIt_Click event:

 

Private Sub cmdTryIt_Click()

 

Print "Now:"; Tab(30); Now

Print "Using DateValue:"; Tab(30); DateValue(Now)

Print "Using TimeValue:"; Tab(30); TimeValue(Now)

Print "Using Weekday:"; Tab(30); Weekday(Now)

Print "Using WeekdayName:"; Tab(30); WeekdayName(Weekday(Now))

Print "Using WeekdayName (abbrev.):"; Tab(30); WeekdayName(Weekday(Now), True)

Print "Using Month:"; Tab(30); Month(Now)

Print "Using MonthName:"; Tab(30); MonthName(Month(Now))

Print "Using MonthName (abbrev.):"; Tab(30); MonthName(Month(Now), True)

Print "Using Day:"; Tab(30); Day(Now)

Print "Using Year:"; Tab(30); Year(Now)

Print "Using Hour:"; Tab(30); Hour(Now)

Print "Using Minute:"; Tab(30); Minute(Now)

Print "Using Second:"; Tab(30); Second(Now)

 

End Sub

 

Run the project and click the "Try It" button. The output should look similar to the following:

The DatePart Function

 

The generic DatePart function returns an Integer containing the specified part of a given date/time value. Thus, it incorporates the functionality of the Weekday, Month, Day, Year, Hour, Minute, and Second functions. In addition, it can used to get the quarter of a given date (1 through 4) , the "Julian" date (the day of the year from 1 to 366), and the week number (1 through 53).

 

Syntax:

DatePart(interval, date[,firstdayofweek[, firstweekofyear]])

 

The DatePart function syntax has these parts:

 

Part Description

interval Required. String expression that is the interval of time you want to return.

 

The string expression can be any of the following:

 

Expression Description Possible Range of Values"yyyy" Year 100 to 9999"q" Quarter 1 to 4"m" Month 1 to 12"y" Day of year 1 to 366 (a "Julian" date)"d" Day 1 to 31"w" Weekday 1 to 7

"ww" Week 1 to 53"h" Hour 0 to 23"n" Minute 0 to 59"s" Second 0 to 59

Date Required. Date value that you want to evaluate. 

firstdayofweek Optional. A constant that specifies the first day of the week. If not specified, Sunday is assumed. 

firstweekofyear Optional. A constant that specifies the first week of the year. If not specified, the first week is assumed to be the week in which January 1 occurs. 

 

To demonstrate DatePart, set up a "Try It" project, and place the following code in the cmdTryIt_Click event:

 

Private Sub cmdTryIt_Click()

Print "Current date/time is: "; _

Format$(Now, "Long Date"); _

Spc(1); _

Format$(Now, "Long Time")

Print "*** DatePart Function Examples ***"

Print "Using 'yyyy':"; Tab(20); DatePart("yyyy", Now)

Print "Using 'q':"; Tab(20); DatePart("q", Now)

Print "Using 'm':"; Tab(20); DatePart("m", Now)

Print "Using 'y':"; Tab(20); DatePart("y", Now)

Print "Using 'd':"; Tab(20); DatePart("d", Now)

Print "Using 'w':"; Tab(20); DatePart("w", Now)

Print "Using 'ww':"; Tab(20); DatePart("ww", Now)

Print "Using 'h':"; Tab(20); DatePart("h", Now)

Print "Using 'n':"; Tab(20); DatePart("n", Now)

Print "Using 's':"; Tab(20); DatePart("s", Now)

 

End Sub

 

 

Run the project and click the "Try It" button. The output should look similar to the following:

Piecing Separate Numbers Together to Form a Date or Time Value

 

In the previous examples, we saw ways to isolate parts of a date/time value. What if you need to go the "other way"? If you have the separate parts of a date/time value in different variables and want to piece them together to formulate a date or time, there are two functions you can use to do this: DateSerial and TimeSerial.

 

The DateSerial takes three numeric arguments: year, month, and day respectively. It returns a date based on those values.

Example:

 

Dim intYear As Integer

Dim intMonth As Integer

Dim intDay As Integer

Dim dtmNewDate As Date

 

intYear = 2001

intMonth = 9

intDay = 2

 

dtmNewDate = DateSerial(intYear, intMonth, intDay)

' returns 9/2/2001

 

The TimeSerial takes three numeric arguments: hour, minute, and second respectively. It returns a time based on those values.

Example:

 

Dim intHour As Integer

Dim intMinute As Integer

Dim intSecond As Integer

Dim dtmNewTime As Date

 

intHour = 11

intMinute = 34

intSecond = 44

 

dtmNewTime = TimeSerial(intHour, intMinute, intSecond)

'returns 11:34:44 (AM)

VB Mondays Dates between a range into Access table

Hi,

I am trying to populate an access database table named DateList that will be used to populate dropdown lists. I want to write code that, from a web page form, will take a "from" date and a "through" date and populate the table's (only) field Date with dates between and including from and through.I only want the date of MONDAY of each week between the two dates.

This is for an online task management tool that I am creating for my department at work.

The reason I need to code this is that other depts will use this as well and each year we want to clear and repopulate the dates and I have written the code to clear the table but now need to repopulate it.l

One of my main concerns here is how to determine how to count the days so that I get Monday's date and increment so thatI do not get say May 35th. Is there a function that keeps track of the actual date so that once I determine the first Monday in the range I can use something like Date() + 7?

ThanksW.
