Look , i have got the following data from

wikipedia

1 light year ( distance travelled by light

in 1 year) = 9,460,730,472,580,800 metres

(exactly)

Speed of light = 299792458 metre/second (

exactly )

So time taken by light to travel a distance

of 1 light year will be

Time = Distance travelled / Time taken

= 9,460,730,472,580,800 /

299792458 Seconds

= 31557600 seconds

Now ,

1 Day = 24*60*60 seconds =

86400 seconds

so, 1 second = 1/86400 seconds

So , converting time taken by for

travelling in 1 light year into days will

give number of days in 1 year wich comes out

to be 31557600 / 86400 = 365.25

So according to this , a year should e

equal to 365.25 days

All I wanted to know is my presumption

right ? Because if you Google the above

question or convert 1 year into days with

Google, it will give the value of 365.242

days . So am i correct or Google is ?

PS - I asked the same question on yahoo answers and got some really ridiculous answers so I decided to aks in the science forum . So please provide some scientific explanation for your answers. Thanx
