Can't read if statement in c [duplicate]

I'm trying to write a program inwhich the user enters the name of a month and the program says if this month has 30, 31 or 28/29 days. Here's the code I'm trying, the problem is that it doesn't reach all the if statement.

#include <stdio.h>

int main() {
    char month;
    
    printf("Enter a month: ");
    scanf("%s", month);

    if (month == "january" || month=="march"|| month == "may" || month == "july" || month == "august" || month =="october" || month == "december")
        printf("This month has 31 days");
    else if (month=="february")
        printf("This month has 28/29 days");
    else if (month == "april" || month == "june" || month == "september" || month == "november")
        printf("This month has 30 days");
    else 
        printf("Enter a valid month");
    
  
    
    return 0;
}

Could someone please help?

Thank you in advance.
