The night sky on your birthday: April 20
April 20 is day 111 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 April 20
On your birthday the Sun stands in front of Aries, even though horoscopes call April 20 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.
Overhead at midnight on April 20
- Northern hemisphere (40°N — New York, Madrid, Beijing): Boötes, Ursa Major, Canes Venatici and Coma Berenices; brightest stars high up: Arcturus (69°), Spica (38°) and Vega (37°).
- Southern hemisphere (40°S — Melbourne, Buenos Aires region, Wellington): Centaurus, Lupus, Hydra and Libra; brightest stars high up: Hadar (70°), Gacrux (68°) and Rigil Kentaurus (68°).
Meteor showers around April 20
Active on your birthday: Lyrids (2 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 April 20, 2027 the Moon will be full moon (100% lit): bright moonlight will wash out the faint stars.
