Why the shepherds?
The appearance to the shepherds shows that the baby being referred to was born when the night time temperature was temperate. Other Scripture may pinpoint the time of year with greater precision.
It is sufficient to understand that the idea that Jesus was born in December is totally precluded by this information.

Why only the shepherds?
Psalm 138:6: Though the LORD be high, yet hath he respect unto the lowly: but the proud he knoweth afar off.
Zechariah 9:9: Rejoice greatly, O daughter of Zion; shout, O daughter of Jerusalem: behold, thy King cometh unto thee: he is just, and having salvation; lowly, and riding upon an ass, and upon a colt the foal of an ass.
Matthew 11:29: Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls.
1 Corinthians 1:26-29:
26 For ye see your calling, brethren, how that not many wise men after the flesh, not many mighty, not many noble, are called :
27 But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty;
28 And base things of the world, and things which are despised, hath God chosen, yea , and things which are not, to bring to nought things that are:
29 That no flesh should glory in his presence.
