The night sky on your birthday: December 1
December 1 is day 336 of the year. Here is what the sky holds for everyone born on it — and a way to get the real sky above the exact place and hour you were born.
The Sun's constellation on December 1
On your birthday the Sun stands in front of Ophiuchus, even though horoscopes call December 1 Sagittarius: the zodiac signs were fixed about 2,000 years ago and the sky has drifted since (precession of the equinoxes). Because the Sun is in Ophiuchus, that constellation is hidden in daylight on your birthday: you see it best around six months later.
