How does JavaScript get the date and year of the current time?

var date = new Date();

date .getYear(); // Get the current year (2 bits)

date .getFullYear(); // Get the full year (4 bits)

date .getMonth(); // Get the current month (0-11,0 for January)

date .getDate(); // Get the current day (1-31)

date .getDay(); // Get the current week X(0-6,0 for Sunday)

date .getTime(); // Get the current time (milliseconds from 1970.1.1)

date .getHours(); // Get the current hour (0-23)

date .getMinutes(); // Get the current minute (0-59)

date .getSeconds(); // Get the current number of seconds (0-59)

date .getMilliseconds(); // Get the current number of milliseconds (0-999)

date .toLocaleDateString(); // Get the current date

var mytime=date .toLocaleTimeString(); // Get the current time

date .toLocaleString( ); // Get the date and time
