Oh...so I went the wrong way!
Assuming you are not counting leap year days that would be 365-345=20...August 28,29,30,31st = 4 days...20-4=
16 so....SEPTEMBER 16th!!! (If my math is correct - math was never my strong point!)
We'll be waiting to wish you a happy birthday...but since my memory is so dang lousy I'll say it now!
HAPPY BIRTHDAY TOM!!!
(a little early is better than missing it!
)
