For fun type in your date of birth and it will give you the day of the week you were born on and how many hours you have lived and other ridiculous stuff like that - have a play
You can also work out how long it has been since your last Smoke 'em in Mokum event too and then realise that you are long overdue a visit
Cheers to you all
