The most accurate statement seems to be in year 3 or 2 BC. But none of this matters since as BR states it is a symbol and it is also about the birth of Christianity.
The birth of Christ is actually the beginning of the age of the Pisces (♓︎) . This is the twelfth and final astrological sign in the zodiac. It is a mutable sign. It spans 330° to 360° of celestial longitude.
It starts in the year 1 and ends in 2150
