We’re giving this gift to all our readers at Christmas time but we hope it will bring you joy throughout 2009 — on whatever date your birthday comes up!

So, without further ado, we commend your attention to the Day of Birth Web site, which is your gateway to a wealth of information on your birthday including: the day of the week on which you were born, your birthstone, your star sign, your Chinese horoscope sign and a fund of other interesting data.

For instance, I’ve just learned that I am currently 20,440 days old, approximately 490,576 hours old and an astronomical 1,766,072,909 seconds old (as of the instant the Day of Birth site received my page request).

For some reason I haven’t yet fathomed, the site also felt it was important to inform me that I am 385 years old in dog years…

Just go to the site and enter the day, month and year of your birth. You’ll get back a long list of personalized birthday trivia including links out to other sites which provide even more fascinating information on historical events that happened on the day you were born.

And… Once you know what day you were born on, you can take this simple, low-tech online personality test, ‘posted’ by Mother Goose:

Monday’s child is fair of face.
Tuesday’s child is full of grace.
Wednesday’s child is full of woe.
Thursday’s child has far to go.
Friday’s child is loving and giving.
Saturday’s child works hard for a living.
But the child born on the Sabbath Day,
Is fair and wise and good and gay.

Happy holidays and have a great 2009!
