Luke 2 8And there were shepherds residing in the fields nearby, keeping watch over their flocks by night. 9Just then an angel of the Lord stood before them, and the glory of the Lord shone around them, and they were terrified. 10But the angel said to them, “Do not be afraid! For behold, I bring you good news of great joy that will be for all the people: 11Today in the city of David a Savior has been born to you. He is Christ the Lord! 12And this will be a sign to you: You will find a baby wrapped in swaddling cloths and lying in a manger.”It is contended by some that Jesus was born in September.

This word is only found in Luke... and translated 3 times as manger and 1 time as stall.
If you read Luke 2:16 carefully you will find that Joseph and Mary and Jesus were all lying in a manger.
It wasn't a manger but a booth... since this was the Feast of Booths.
