DateAdd ( interval, number, date )

DateAdd ("m", 4, #20/11/2013#)

Alex, that is months and not MS formatted date.

For the 4 years prior to current date.

IssueDate > DateAdd("yyyy", -4, Date())

[AlexHedley]

Doh! It's not even a minus, don't know where my head was at!

Corrected:
DateAdd ("yyyy", -4, DateValue)

Originally posted which was incorrect:
DateAdd ("y", -4, DateValue)

Don't know why, but single "y" doesn't work. The function will default to "d" unit. Have to use "yyyy".

Perhaps this can also help clear thing up, the following identifies characters you can use to create user-defined date/time formats:

c Display the date as ddddd and display the time as ttttt, in that order. Display only date information if there is no fractional part to the date serial number; display only time information if there is no integer portion. d Display the day as a number without a leading zero (1 – 31). dd Display the day as a number with a leading zero (01 – 31). ddd Display the day as an abbreviation (Sun – Sat). dddd Display the day as a full name (Sunday – Saturday). ddddd Display the date as a complete date (including day, month, and year), formatted according to your system's short date format setting. The default short date format is m/d/yy. dddddd Display a date serial number as a complete date (including day, month, and year) formatted according to the long date setting recognized by your system. The default long date format is mmmm dd, yyyy.
w Display the day of the week as a number (1 for Sunday through 7 for Saturday). ww Display the week of the year as a number (1 – 54). m Display the month as a number without a leading zero (1 – 12). If m immediately follows h or hh, the minute rather than the month is displayed. mm Display the month as a number with a leading zero (01 – 12). If m immediately follows h or hh, the minute rather than the month is displayed. mmm Display the month as an abbreviation (Jan – Dec). mmmm Display the month as a full month name (January – December).
q Display the quarter of the year as a number (1 – 4). y Display the day of the year as a number (1 – 366). yy Display the year as a 2-digit number (00 – 99). yyyy Display the year as a 4-digit number (100 – 9999). h Display the hour as a number without leading zeros (0 – 23). Hh Display the hour as a number with leading zeros (00 – 23). N Display the minute as a number without leading zeros (0 – 59). Nn Display the minute as a number with leading zeros (00 – 59). S Display the second as a number without leading zeros (0 – 59). Ss Display the second as a number with leading zeros (00 – 59). t t t t t Display a time as a complete time (including hour, minute, and second), formatted using the time separator defined by the time format recognized by your system. A leading zero is displayed if the leading zero option is selected and the time is before 10:00 A.M. or P.M. The default time format is h:mm:ss. AM/PM Use the 12-hour clock and display an uppercase AM with any hour before noon; display an uppercase PM with any hour between noon and 11:59 P.M. am/pm Use the 12-hour clock and display a lowercase AM with any hour before noon; display a lowercase PM with any hour between noon and 11:59 P.M. A/P Use the 12-hour clock and display an uppercase A with any hour before noon; display an uppercase P with any hour between noon and 11:59 P.M. a/p Use the 12-hour clock and display a lowercase A with any hour before noon; display a lowercase P with any hour between noon and 11:59 P.M. AMPM Use the 12-hour clock and display the AM string literal as defined by your system with any hour before noon; display the PM string literal as defined by your system with any hour between noon and 11:59 P.M. AMPM can be either uppercase or lowercase, but the case of the string displayed matches the string as defined by your system settings. The default format is AM/PM.

That's for formatting a date value, which results in a text string value. DateAdd doesn't work with all those parameters as you might think - as seen with "y" and "yyyy".

[naeemahmad]

Got it. I just wanted to provide additional resource to help identify all options of formatting. Thank you for clearing that up, definitely not my intention to help confuse. We have enough confusion without help.. lol.
