1 day
1 hour

Do you want the difference between the month parts
Difference between the dateparts and the Difference
Between yearparts.. ....(That will be like what you have written above ...but seems useless..)

or

You want the exact Number of days,months,Years etc.. between two given dates in different format ?

Use the DateDiff function.

Here is the syntax for the DateDiff function.

Syntax

DateDiff(interval, date1, date2[, firstdayofweek[, firstweekofyear]])

The DateDiff function syntax has these named arguments:

Part - Description
interval - Required. String expression that is the interval of time you use to calculate the difference between date1 and date2.
date1, date2 - Required; Variant (Date). Two dates you want to use in the calculation.
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.



Settings

The interval argument has these settings:

Setting - Description
yyyy - Year
q - Quarter
m - Month
y - Day of year
d - Day
w - Weekday
ww - Week
h - Hour
n - Minute
s - Second

Usage

?DateDiff("m", "11/11/11", "12/12/12")

thanks matthew

that was really helpful..emm.. wondering where could i find good reference on built in vb functions plus the syntax..

If you are using VB, and have it installed along with a help file (or MSDN Libary), everything is listed in there.
