Calculating next x anniversary dates

[NeoPa]

I've no idea who set the best answer to post #14, but as it's clearly a long way from being so I've reset it.

I would have selected one earlier but there are a number of good answers with some good techniques illustrated.

As Stewart's seems now to be the most succinct I will set that one, but I would certainly comment that Topher's post #10 deserves an Honourable Mention.

I've never seen a practial use of DateSerial before - that's quite elegant. Thanks, Stewart!
