The last sign, and drawn as two fish tied together swimming in opposite directions. Pisces is given the edges of things — sleep, art, dreams, doubt — and closes the cycle by dissolving the boundary the previous eleven spent building.
The dates above are the conventional ones and hold for most years. The Sun actually crosses into Pisces at a slightly different moment each year — by up to a day — so a birth on February 19 or the day before can land on either side depending on the year and the hour.
If the birthday is on that edge, check it with the zodiac lookup using the exact time and place rather than a printed range.
