The night sky on your birthday: August 13
August 13 is day 226 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 August 13
On your birthday the Sun stands in front of Leo, which here matches the horoscope sign Leo. Because the Sun is in Leo, that constellation is hidden in daylight on your birthday: you see it best around six months later.
