The Day of One's Birth

The celebration of birthdays year after year is not something we should be doing. Although, the day of one's actual birth is praiseworthy and a joy beheld by the parents and shared with family, as children are gifts from Elohim, but to make a yearly party out of it doesn't lead to anything good. Yes, this includes the pagan celebration called Christmas that many people have been duped into thinking as the day Messiah was born.

As punishment for disobeying that one commandment: 

Genesis 3:16 To (Eve) He said, "I will greatly multiply your pain in childbirth, in pain you will bring forth children....

Should we celebrate the day, elevating ourselves to such importance, forgetting that we caused our mothers great physical pain?

Pharaoh had his chief baker impaled during his birthday party: 

Genesis 40:20 Now the third day was Pharaoh’s birthday, and he gave a feast for all his officials. ... He restored the chief cupbearer to his position, so that he once again put the cup into Pharaoh’s hand— but he impaled the chief baker, just as Joseph had said to them in his interpretation of the dream.

Job makes sin offerings for his sons who celebrate their birthdays: 

Job 1:4 And his sons went and had a feast in the house of each on his day, and sent and invited their three sisters to eat and to drink with them. And it came to be, when the days of feasting had gone round, that Job would send and set them apart, and he would rise early in the morning and offer burnt offerings – the number of them all – for Job said, “It might be that my sons have sinned and cursed Elohim in their hearts.”

John the Immerser is beheaded at Herod's birthday party: 

Matthew 14:6 But when Herod’s birthday came, the daughter of Herodias danced before the company and pleased Herod, so that he promised with an oath to give her whatever she might ask. Prompted by her mother, she said, “Give me the head of John the Baptist here on a platter.” And the king was sorry, but because of his oaths and his guests he commanded it to be given. He sent and had John beheaded in the prison, and his head was brought on a platter and given to the girl, and she brought it to her mother. 

With that scenario in mind, I will include a link to this information:

Bad Dancing

There is nothing wrong with knowing how many years we have lived. Knowing the age of people was kept track of since there were age requirements in regards to taxes and military service. The ages of those recorded in the genealogies give us a time frame to work with in our studies. It is the adopted pagan practice of celebrating the day with drinking, eating and dancing (party time) that has been passed on down through the generations that we should stop doing.  

Birthday celebrations are actually rooted in paganism. The Encyclopedia Americana (1991 edition) states: "The ancient world of Egypt, Greece, Rome, and Persia celebrated the birthdays of gods, kings, and nobles."
Authors Ralph and Adelin Linton reveal in their book The Lore of Birthdays: "Mesopotamia and Egypt were also the first lands in which men remembered and honoured their birthdays. The keeping of birthday records was important in ancient times principally because a birth date was essential for the casting of a horoscope."
So, there is a direct connection between the Pagan practice of birthday celebrations and astrology (horoscopes and fortune telling).

Also, The World Book Encyclopedia (volume 3, page 416) states:

"The early Christians did not celebrate [Y'shua's] birth because they considered the celebration of anyone's birth to be a pagan custom." 

Down to the fourth century Christianity rejected the birthday celebration as a pagan custom.

Notice also the record of the first century historian Josephus: The Jews in Christ’s day knew God’s attitude toward birthday celebrations, “Nay, indeed, the law does not permit us to make festivals at the births of our children” (Flavius Josephus, Against Apion, Book II, section 26).
