How do you remember zodiac sign in order?

In some ways the simplest way is to learn them like the months of the year--there are only twelve, so it shouldn't take too long.

But there are rhymes too:

The RAM, the BULL, the heavenly TWINS,

And next the CRAB, the LION shines,

The VIRGIN and the SCALES;

The SCORPION, ARCHER and SEA-GOAT,

The MAN who pours the water out

And FISH with glittering tails.

OR

In March the springtime RAM begins,

Then comes the BULL, in May the TWINS;

The CRAB in June, next LEO shines,

And VIRGO ends the summer signs.

The BALANCE brings autumnal fruits,

Then SCORPION stings and ARCHER shoots;

December's GOAT brings wintry blast,

AQUARIUS rain, the FISH come last.
