Discover the logic and find the number for September = ?

PS: Please support your answer by logic.

Answer 1

First Digit: The total number of letters present in the word
Second Digit: Position of month
Third Digit: Number of Vowels in the word
Fourth Digit: The sum of letter a and y present in the word

For fourth digit
January = 2a +1y = 3
February = 1a + 1y = 2
March = 1a = 1
April = 1a = 1
May = 1a + 1y = 2
June = 0a + 0y = 0
July = 1y = 1
August = 1y = 1
September = 0a + 0y = 0
The number for September is 9930

Answer 2

September = 9932

First Digit: 9 letter in the spelling of September
Second Digit: September is the ninth month
Third Digit: Number of Vowels in the spelling of September i.e. 3

last digit is square root of there sum of there ranks of alphabets
eg
may: M=13, A=1, Y=25, sum is 49, 4+9=13, 1+3=4: sq root of 4 is 2..

Similarly:
S=19 e=5 p=16 t=20 e=5 m=13 b=2 e=5 r=18
=> total =103=4,
=> sq root of 4 is 2,
=> so overall 9932
