Logically every 7 years - but I'm pretty sure days don't follow one by one and leap-years will bugger it up.
If I find an app for it I'll post.
well I havent looked this up but doesnt it fall on the next day except when its a leap year when it falls the day after so that would make it once in 8 years on average over an 80 year period unless that period includes one of the funny leap year rules.
Well to save everyone the pointless and brain numbing exercise of calculating their own equations, lets choose the most common birthday which is Christmas Day.
Sorry if that spoiled a pub wind up.

You're right in saying it falls on the next day each year and two days later in a leap year, but this means it will fall on the same day every six years, or if there are two leap years within those six years (are you following this?), then the day will be repeted after five years.
To expand on Chief-Kaiser's explanation a bit, there are also the years when the day of birth is skipped over by the leap year. The number of years between the birthday falling on the day of birth runs in a repeating sequence:
6, 5, 6, 11, 6, 5, 6, 11, 6, 5, 6, 11, 6, etc.

If Redwine Lover was to do a similar list for himself, would I be able to sue him due to the RSI I would receive from scrolling down?

Nah... it wouldn't fit on one page so you'd just have to flick over three pages rather than scrolling! :mrgreen:

Thanks for pointing that out. So what there is, is a 28 year cycle (6+5+6+11) in which time your birthday will fall on the same day 4 times, (or on average once every seven years).Which is of course quite logical.
So if you die aged 28, 56, 84 or 112, the answer is simply to divide your age by 7, less easy if you die at a different age!
Unless your birthday is 29th February in which case you have to wait 28 years for your birthday to fall on the same day. Phew!
Ahh bollocks to all this lol I just look at next years calendar thats enough notice for me. Not as though I am in any rush smile
