The Witnesses will tell you that there are only two birthday celebrations in the Bible and on those days, someone was killed. Also those celebrating their birthdays were non-christians. thus they reason that God recorded these two birthdays to teach us that they are wrong to observe. But, you have to assume that these two birthdays are telling us that all birthday celebrations, even that of Christians, would be wrong. Because the Bible does not specifically state that they are wrong. What was wrong about the two they cite, is that someone was killed on those days. It was not the act of observing a Birthday in itself that was wrong but the fact that these men used thier birthdays as an excuse to kill people. Here are the two they will read to you: Genesis 40:20, Mark 6:17-28.
Here is a third birthday celebration they conveniently leave out:
8 And there were shepherds living out in the fields nearby, keeping watch over their flocks at night. 9 An angel of the Lord appeared to them, and the glory of the Lord shone around them, and they were terrified. 10 But the angel said to them, "Do not be afraid. I bring you good news of great joy that will be for all the people. 11 Today in the town of David a Savior has been born to you; he is Christ [ a ] the Lord. 12 This will be a sign to you: You will find a baby wrapped in cloths and lying in a manger."
13 Suddenly a great company of the heavenly host appeared with the angel, praising God and saying,
14 "Glory to God in the highest,
and on earth peace to men on whom his favor rests."
15 When the angels had left them and gone into heaven, the shepherds said to one another, "Let's go to Bethlehem and see this thing that has happened, which the Lord has told us about."
16 So they hurried off and found Mary and Joseph, and the baby, who was lying in the manger. 17 When they had seen him, they spread the word concerning what had been told them about this child, 18 and all who heard it were amazed at what the shepherds said to them. 19 But Mary treasured up all these things and pondered them in her heart. 20 The shepherds returned, glorifying and praising God for all the things they had heard and seen, which were just as they had been told.
Noticed how the Angels and men rejoiced on the birthday of Christ? No JW will quote this birthday to you.
The Apostle Paul taught Christians in the early congregation that days of observance were up to the individual Christians. And that no matter what day we choose to observe, we should do it keeping in mind that we are Christians and not using this day as an excuse for loose conduct. However Paul did not prohibit the observing of any days, including birthdays.
5 One man considers one day more sacred than another; another man considers every day alike. Each one should be fully convinced in his own mind. 6 He who regards one day as special, does so to the Lord. He who eats meat, eats to the Lord, for he gives thanks to God; and he who abstains, does so to the Lord and gives thanks to God
