1984 leap month? What month?

1984 has no leap month, but there are 12 months in normal years! The date of neutral heavy snow is in the first half of abortion, so it is winter month. In1February, there is a winter solstice at the beginning of the first month, a slight cold on the 15th (the first half of the month) and a severe cold on the 30th. Am I right? If someone can prove me wrong, I am willing to bear all legal responsibilities!
