The dates printed beside each sign are a convention. The Sun crosses from Aries into Taurus at one exact moment, and that moment moves: about six hours later each year, then back a day in leap years. So on April 20 the answer depends on the year, and in some years on the hour.

The sign: Taurus
Taurus is fixed earth, the sign of what lasts. Venus rules it, so its natives are builders with taste: patient, loyal, hard to hurry, and at home wherever there is good bread, good cloth and a promise kept. They hold on, to people and to positions alike, and their strength is the calm that others lean on.
The first decan, and what it changes
The first decan is Venus twice over. This is Taurus at its most sensual and most settled: a love of beauty, comfort and good company, and a patience that can look like slowness until the result is seen.
The sign: Aries
Aries opens the zodiac at the spring equinox, and its natives carry that beginning in them. Fire in its first, cardinal form: they start things, say the plain word first, and recover from a fall faster than anyone. Mars gives them courage and a short fuse; their work in life is to finish what they begin.
The third decan, and what it changes
The third decan is touched by Jupiter, through Sagittarius. The impulse widens into purpose: these natives fight for a cause rather than a quarrel, travel far, and are the luckiest and most philosophical of the Aries born.
