The night sky on your birthday: December 19
December 19 is day 354 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 19
On your birthday the Sun stands in front of Sagittarius, which here matches the horoscope sign Sagittarius. Because the Sun is in Sagittarius, that constellation is hidden in daylight on your birthday: you see it best around six months later.
Overhead at midnight on December 19

Meteor showers around December 19
Active on your birthday: Geminids (5 days from peak). On a dark night away from city lights you can make a wish on a real shooting star.
The Moon on your next birthday
On the evening of December 19, 2026 the Moon will be waxing gibbous (77% lit): bright moonlight will wash out the faint stars.
