Golden birthday

the birthday when you turn the same age as your birthdate.

The ‘Golden Birthday’ is the day where a human being turns the same age as the date to which they were born (Example, turning Twelve on the 12th of October). All humans will experience this day, whether it be when they are one years old or 31 years old; that is to say, except for a select few individuals born on the leap year – sadly, these humans will never experience the Goldenness of such a day and are forced to live out their lives in anguish and despair.
However, not all Golden Birthdays are considered equal. Based on an ancient astro-scientological belief said to stem from a Magic Wizard Book crafted during, and as a result of, the Big Bang itself, each number to which ones Golden Birthday lands upon holds different levels of power. Single digit Golden Birthdays are the least potent of the Golden Birthdays, and are generally harmless to those who do not know how to wield the Power. Other relatively harmless Golden Birthday numbers include 27, 28, 29, 30, 17 and 20. The rest of the Golden Birthday numbers vary in Power (If you would like to learn more, please consult the Magic Wizard Book). It is quite important to note, however, that the two most Powerful Golden Birthdays are 31 and 23. While 31 is stable and at a constantly high Power level, 23 is an ever-shifting entity that at times holds nearly infinite levels of Power. This can be dangerous and has the potential to unknown chaos, depending on if the wielder (birthday boy/girl) is aware and can harness the Power.

When you turn the same number as the number of the month your birthday falls on (eg. 22 on January 22). This birthday is the on,y birthday you are guaranteed to get laid. You must go to the bar regardless of age or relationship status and enjoy getting your golden kill.
