So, as you probably know, I've done 2 raffles asking about bdays. One about month, second about day of the month.

You can find the polls here and here, but I want to give my summary, too.

First of all, those 2 polls have a huge difference of votes: 373 on months, 493 on days. This was probably caused because the second poll had a lot of answers which made more people pay attention to it, but I have no idea if that made it less trustworthy or no.

Now, months. At first I was certain that March is going to win, it held the first position for long and we saw a lot of bday raffles in march this year. But, surprisinlgy, it came in 2nd. Also, November holds place as the least popular one, despite the fact that the month before and after have much more votes.
It seems the most people are born in Spring with 104 votes, followed by Winter with 96, Autumn with 87 and Summer with 86.

Now let's move to days of month. I'm not sure if people actually voted for the true one or just saw a bunch of numberd and decided to click the random one, but let's assume the better. 

So, it seems like the difference between days isn't very big, but the top spot takes "15th" with it being followed by 1st, 2nd, 20th and 8th. An interesting set of numbers, to be honest. Also, I expected 31st to be last, since it occurs in 7 months out of 12, but, surprisingly, 22nd is last with mere 9 votes.
