Mr. Hikiko is the emperor of a planet called Biku. He got a gift from planet earth which can count time in seconds. Now he wants to make a system which can convert seconds to a time & date format. His idea is to make one like planet earth but a bit simpler. He wants that a month will be exactly 30 days and a year will be 12 months which is 360 days. And the time format will be 12-hour formats. Year counting will be start with year 1 and so on.
