1February 25th Japan is the birthday of Mithra, the Persian sun god (that is, god of light), and it is a pagan festival. At the same time, the sun god is also one of the gods of Roman Catholicism.
This day is also the winter solstice festival of the Roman calendar. The pagans who worship the sun god regard this day as the hope of spring and the beginning of the recovery of everything. For this reason, the Roman church chose this day as Christmas.
Since 1 February 25th was recognized as Christmas by most churches, the original epiphany of 1 February 6th was inaugurated to commemorate the baptism of Jesus, but the Catholic Church designated1February 6th as the "Three Kings' Day".
To commemorate the story of the three kings of the East (that is, three doctors) who came to worship when Jesus was born. With the widespread spread of Christianity, Christmas has become an important festival for Christians of all denominations and even non-Christians.
