I have seen a lot of info on how to subtract one datetime from the other and how to add years on to a datetime. but the following is giving me a headache....

When a user inserts a record a hidden field called subdate with a value of datetime.now is added to the db.

I then need to have an 'old records' page that lists all the entries that are over 1 year old and was hoping to use something (but using subtract method) similar to;

(DateTime.Now.AddYears(1))

but there is no SubtractYears available? Why?

Please can you let me know how I achieve the same result?
