A friend sent me this riddle and I can't figure out a solution:
January = 251017
February = 25628
March = 81335
April = 12145
May = 251353
June = 51064
July = 251074
August = 20186
September = ?
So the question is:
What number is September?
He said this question was taken from an FBI exam but I doubt that.

The answer is
181999
To form the number take
(i) the location in the alphabet of the last letter, R=18,
(ii) the location in the alphabet of the first letter, S=19,
(iii) the position of the month in the calendar, September=9,
(iv) the number of letters in the name of the month, September=9,
and concatenate 18+19+9+9 = 181999

@Strawberry August is 20+1+8+6=20186, by the same reasoning. The code for each month is formed in the same way.

Welcome to Puzzling SE. Remember to check if other people have already posted the solution you intend to or if a solution has already been accepted. In this case the answer you have was posted a few hours ago by someone else and been accepted.

First of all, there is no way to really know who voted on your question and there is no benefit in trying to guess anyways as no one can change someone else's vote except the person who made it. Secondly, Votes are used to indicate level of usefulness, effort and research put into a question or answer. An answer that has already been posted by someone else shows minimal research and effort as they didn't look at the page even (and may have simply copied) and even if they did come to it on their own, it ultimately isn't useful or helpful to anyone else as it doesn't contribute anything new.

Try not to take it personally (I get it can be hard not to sometimes) but votes are simply a way of filtering the obscene amount of content on this site. Just try to learn from your mistakes and you'll get the hang of it.
