About the combination "Birthday numbers"

Birthdays are the most emotional way to play the lottery. A child's birthday, your own wedding anniversary, the date of a special moment. That makes the numbers meaningful, but unfortunately also predictable. Millions of people pick according to exactly this pattern, and all of them stay within the range of 1 to 31, because no month has more than 31 days.

The result: the high numbers from 32 to 49 are systematically neglected, the low ones heavily over-played. If a pure birthday combination were drawn, the prize would have to be shared with an above-average number of people. The probability of winning is exactly the same as for any other combination. Birthdays don't win less often, but if they hit, you share with more people.
