My question is this, How do you tell which constellation the Sun is in on a given day? Can anyone please help me??

Due to an effect called precession (the 26000-year wobble of the Earth's axis), dates given by astrologers in their wacky columns are hopelessly out of date.

Also, only 12 constellations are listed, whereas the Sun actually passes through 13 (the 13th one being Ophiuchus).

Anyway, hope these dates will help answer your question.
(Data taken from http://www.griffithobs.org/SkyOphiuchus.html)

Constellation

Capricornus:>> January 19 to February 15
Aquarius:>> February 16 to March 11
Pisces:>> March 12 to April 18
Aries:>> April 19 to May 13
Taurus:>> May 14 to June 19
Gemini:>> June 20 to July 20
Cancer:>> July 21 to August 9
Leo:>> August 10 to September 15
Virgo:>> September 16 to October 30
Libra:>> October 31 to November 22
Scorpius:>> November 23 to November 29
Ophiuchus:>> November 30 to December 17
Sagittarius:>> December 18 to January 18


Unfortunately, dates seem to vary slightly, depending on the source of the information! Here is another variation which I've found from another website at:

Constellation

Capricorn:>> January 21 - February 16
Aquarius:>> February 17 - March 11
Pisces:>> March 12 - April 18
Aries:>> April 19 - May 13
Taurus:>> May 14 - June 21
Gemini:>> June 22 - July 20
Cancer:>> July 21 - August 10
Leo:>> August 11 - September 16
Virgo:>> September 17 - October 30
Libra:>> October 31 - November 23
Scorpio:>> November 24 - November 29
Ophiuchus:>> November 30 - December 17
Sagittarius:>> December 18 - January 20

Whatever way you look at it, at the moment the Sun is in the '13th' constellation of Ophiuchus.
