Quite the opposite here. My birthday is short before x-mas. When my wife was awaiting twins the date was calculated for the 26th of decembre. So we decided to invent families and friends for a bigger party at my birthday before she would have to be forced to mainly resting. But around 9:30pm it started, too much party, or just because you never now with twins. The boy was born minutes before midnight, the girl short after.
So the only curse is that only a few people remember at the birthday of the twins that it is my birthday too
And the same curse all people with a birthday around
