What is the date when the Aquarius is biased towards Pisces?

The birth date of this constellation is between 18 February and 19 February.

February 19 happens to be the constellation handover day. People born on the constellation handover day need to have the time of birth (year, month, day and hour) and place of birth to determine whether the sun constellation is Aquarius or Pisces. Aquarius Pisces is a constellation between Aquarius and Pisces. This constellation has both the eccentric character of Aquarius and the dreamy character of Pisces.
