Well a half second is 50 centaseconds(500 millaseconds)(500 thousand million zeptoseconds) and there is 60 seconds in a minute 60 minutes in a hour 24 hours in a day and there is 365.25 days in a year so 60 x 60 x 24x 365.25 =31557600(thirty one million five hundred fifty seven thousand six hundred) that is how many seconds in the type of year we think of besides that kind of year you will have to look them up and... oh yeah! I forgot you are asking how many half seconds well then 31557600 x 2 = 63115200(sixty three million one hundred fifteen thousand two hundred) well then there you have it that is the answer to your question-''how many half seconds in a year.'' Okay and one more thing that isn't the exact number of seconds in a year because each day is 55 billionths of a second longer than the day before it so it is time to do some more math...and I'm not doing it. But if you want to do it I will tell you how to figure it out. Earth is about 3.5 billion years old (3 billion 500 million years) and again each day is 55 billionths of a second so figure it out.And I have to go because my mom made me dinner p.s. I am actually a second grade boy.
