Is the cancer star sign from June 21 - July 21 or does cancer last longer my birthday is July 22 different websites say different things so could you please help find an answer?

Hmm. I have many horoscope magazines and books and its says the cancer star sign is June The 22nd - July The 22nd. Because my friends b-dayy is on the 23rd of July and she is a Leo. So Im sorry but this answer was infactually wrong before. I hope i corrected it properly and if the last writer before me has any questions or would like to say something then please do.
