there can be more than one solution to this riddle if you really analyze it. in one case there can be 12 seconds because there are 12 months in a year and every month has a "second". (Jan. 2, Feb. 2 etc.) or there can be 24 seconds when you look at it as every month having 2 "seconds" (Jan. 2, Jan 22, Feb. 2, Feb. 22)
