A Statistical post.

The last of my children celebrates a birthday for this year today, as it is Katie's 21st. She is 21 on the 21st, Harry was 17 a few days ago on the 17th, and Hannah was 23 back in February on (you guessed it) the 23rd.
Your golden birthday is when the date you celebrate corresponds with your age.  All three of my children have celebrated their golden years within one year.  I'm not sure what the probability of three siblings celebrating a golden birthday within one year is.

Being a bit of a geek I had to find out, and this page gave me a little help...the probability is approximately 1 in 10,000.  pretty low then.

After all of these mathematical gymnastics, here is Katie's card.  I used WRMK pocket page cards, some Sizzix die cuts and a little chevron tape.

Happy birthday Katie; enjoy your golden day.

Goodness me - did you plan it that way 23 years ago? I'm glad mine don't have their golden birthdays in the same year - it would have meant my daughter being born on Christmas Day!

Gorgeous card but surely you will be doing a special page about your 1 in 1000 chance!

I think it probably deserves a page, it might help me use up some of those number Thickers that always seem to be left over.
