What is the common noun and proper noun in the sentence, “parker’s birthday is january 27.”

The answer of the question is "Parker's"

I think that the proper noun is Parker's and the comoon nour is birthday but im not totally sure

in this text, paine use the word “ye” several times in order to  capture  the  attention of the colonists who   haven't understand the   importance and urgency of his cause. the word "ye" that is the plural of   "thou" is used to call the colonists attention and make the fight for the cause.
