what time is it that's a very good question from morning until night clocks

help us to plan our day they tell us when things begin and when they end

moving across the sky the time it takes for the earth to make

one complete turn is called a day a day is divided into hours minutes and seconds

there are 24 hours in a day there are 60 minutes in an hour

how many minutes are there in a day multiply 24 hours times 60 minutes to

there are 1440 minutes in one day we measure Time by other movements too

the Earth travels around or orbits the Sun the time it takes for the earth to go

around the Sun once is called a year one year is equal to 12 months or

just over 52 weeks to be very accurate it takes the earth

365 days 5 hours 49 minutes and 12 seconds to go around the Sun

we divide the earth into 24 time zones each time zone is one hour apart from

the next time zone for example when it is 10 AM where you live it is 10 pm on

the opposite side of the world in two hours it will be noon where you

live but on the other side of the world it will be 12 at night

thanks to clocks and calendars we can measure time very easily however it is

the movement of the earth that really allows us to measure tim
