That is what they said of me at the time. 99 stands for 1999. The rest you can figure out...
Well, I suppose it means you were born in '66 and your 33rd birthday was in '99. But that's not really all that magical. Quite a few people alive today were born in 1966, probably somewhere between 1% and 2% of the world population, and each and every one of them turned 33 in 1999. Who'd have imagined that?
Or perhaps your 66 doesn't just stand for 1966 but also means you were born on the 6th of June. That would make you 365 times as special as someone who was "only" born in 1966.
I note your login name includes '66', but that in itself is not enough to suggest how likely it is that you were born in 1966 or on the 6th of June or both.
I don't know what's so special about 33. Perhaps it has roots in Rumanian folklore. Perhaps it's just "twice as special" as 3, which is pretty special because, well, it just is. Even apart from the Holy Trinity. Or perhaps there's a personal or family connection.
I think 7 is pretty special, together with its multiples. My parents, my sister, and I were all born in different months, but both my parents were born on the 7th day of their birth months. Put 7 and 7 together and you get 14, so I was born on the 14th. Guess when my sister was born. Yes, on the 28th.
