The night sky on your birthday: July 30
July 30 is day 212 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 July 30
On your birthday the Sun stands in front of Cancer, even though horoscopes call July 30 Leo: 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 Cancer, that constellation is hidden in daylight on your birthday: you see it best around six months later.

Meteor showers around July 30
No major annual meteor shower is active on this date — the sky is all stars and planets.
The Moon on your next birthday
On the evening of July 30, 2027 the Moon will be waning crescent (9% lit): a dark sky, good for stargazing.
