JavaScript program to display the current Day and Time
In this program, we will print the system's current day and time in the format of a 'day of weeks' hours: minute: second 'pm or am'.
getDay() is a method of date() object, it will return the current day of weeks in integer form between 0 to 6: Where 0 for Sunday, 1 for Monday, 2 for Tuesday, and so on.
similarly, getHours() is a method of date and it will return current hours in integer from 0 to 23. but below the given program, we have converted it into 12 hours clock i.e hour%12.
getMinutes() will return the minute of the current system time in integer from 0 to 59.
getSeconds()will return the current system second in integer from 0 to 59.
