New year kit

The ancient Babylonian calendar was lunisolar, and around the year 2000 BC^[5] began observing a spring festival and the new year during the month of Nisan, around the time of the March equinox. The early Roman calendar designated 1 March as the first day of the year.^[6] The calendar had just 10 months, beginning with March. That the new year once began with the month of March is still reflected in some of the names of the months. September through to December, the ninth through to the twelfth months of the Gregorian calendar, were originally positioned as the seventh through to the tenth months. (Septem is Latin for "seven"; octo, "eight"; novem, "nine"; and decem, "ten") Roman mythology usually credits their second king Numa with the establishment of the two new months of Ianuarius and Februarius.
