Dim today As Date today = Now() today = DateSerial(Year(today ), Month(today ), Day(today)). A much more efficient way to do it is to use the various date/time functions. While one way to do that is to convert the date to a formatted string and then convert the string back to a date, it’s extremely inefficient. ![]() If you plan to do a comparison for equality, make sure that you TRUNCATE your date/time value to only the date. but the function Now() will return a value that may have any time value at all. will create a date/time value that is equal to. However, you do need to be careful when comparing dates for equality. There is absolutely NO reason to convert dates to strings to perform comparisons for greater than or less than. Therefore, will be greater than, because 29 is greater 01. will give the wrong result approximately HALF THE TIME, because string comparisons will compare the day number BEFORE comparing the month number or year number. If Format(myDate, "dd/mm/yyyy") > Format (Now(), "dd/mm/yyyy"). ![]() *Ĝomparison as dates if much faster than comparison as strings *Ĝonversion to formatted strings adds even more unnecessary processing time * String conversions can lead to incorrect results If you have dates in the form of Date values (for example, if you retrieve the value from a Date/Time field to a Date variable, or if you get the value of the Now() function), you should compare them AS DATES:
