Separate the date and month either by using substring or regular expressions.

Once you have the month, you will need to convert it into an integer. Use an array of months and the index which matches is the number.

Then, use the Date object methods to set the dates and compare using > or < (after adding 31 to the first date).

How will I calculate if it will be a date of december last year and january this year.

If you compare, JavaScript will do this for you. When you add 31 days to a date, it will automatically go to the next month/year.
