What's your actual astrological sign?
The astrological signs used these days are 2000 years out of date.
The reason is due to the slow, 25,800 year wobble (precession) of
Earth's rotation axis.
The traditional linking of birthdays and birth signs suggests the sun
spends about 30 days crossing each of the 12 zodiacal constellations.
The truth is that there are really 13 constellations that the sun "drifts"
through along it's path in the sky (the ecliptic).
Another truth is that they are not equal in duration.
They vary from 6 days to 45 days.
Below is a table describing the actual 13 zodiacal constellations.
The reason the column "Actual (2000 AD)" includes the same
ending day of one as the beginning day of the next is that the
movement of the sun from one constellation to another
happens during the day, not at the actual end of the day.
In the old, traditional one each sign has the same time span.

Someone could use the actual zodiac to produce an up-to-date astrological chart
to continue to fool the gullible. The drawbacks are that it would be much more
complicated with all the different time durations and the "bad" number 13 would
have to be used.
