The night sky on your birthday: May 13
May 13 is day 134 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 May 13
On your birthday the Sun stands in front of Aries, even though horoscopes call May 13 Taurus: 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 Aries, that constellation is hidden in daylight on your birthday: you see it best around six months later.
