Cancer Dates of Birth
The Zodiacal Sign of Cancer commences on June 22st, but for days it does not come into full power until on or about June 28th. From this date onwards it is In full strength until July 20th, and is then for seven days gradually losing its strength on account of becoming overlapped by the "cusp" of the incoming sign Leo.
Cancerians love home-life, family and domestic settings. They are traditionalists, and enjoy operating on a fundamental level. They love history, and are fascinated with the beginnings of things (heraldry, ancestry, etc.). The moon is their ruler, so they can be a bit of a contradiction and sometimes moody. However, they are conservative, so they’ll be apt to hide their moods from others altogether. They have a reputation for being fickle, but they’ll tell you that isn’t true, and it’s not. Cancerians make loyal, sympathetic friends. However Cancerians need alone time, and when they retreat, let them do so on their terms.
Cancer Dates: June 22 – July 22
In astrology, your Cancer Zodiac sign (also called sun sign or star sign) is decided by the position of the sun at the moment of your birth, as seen from Earth. The sun takes a year to travel through the twelve Zodiac signs, but it’s not exactly a year of 365 days. The time it takes is closer to 365.25 days. That’s why we have leap years.
Every fourth year we add a day to the calendar, the 29th of February, making that year 366 days. Actually, there’s an additional rule, to make it more precise with the actual movement of earth and the sun: the starting year of a new century is not a leap year, unless it’s evenly divisible by 400. So, 1900 was not a leap year, but 2000 was.
The leap years make the dates of each Zodiac sign change slightly. Normally, Cancer starts on June 22 and ends on July 22, but that’s just the mean. In reality it changes slightly in a four year period from one leap year to the next.
If you were born on the 22nd of June or the 22nd of July, you have to check if you’re really a Cancer or not. It never differs more than a day in each direction. The start of Cancer must be within the 21st to 22nd of June, and the end of it within the 22nd or 23rd of July. People born on other dates need not be concerned.
