JavaScript Date prototype Property

Below is the example of Date prototype Property. 

• Example:
  

javascript

<script>

  var birthday = new Date('June 21, 2018 16:44:23');
  var date1 = birthday.getDate();
  var day1 = birthday.getDay();
  var year1 = birthday.getFullYear();
  var hour1 = birthday.getHours();
  var ms1 = birthday.getMilliseconds();
  var m1 = birthday.getMinutes();
  var mth1 = birthday.getMonth();
  var time1 = birthday.getTime();
  var s1 = birthday.getSeconds();
  var offset = birthday.getTimezoneOffset();
  var date2 = birthday.getUTCDate();
  var day2 = birthday.getUTCDay();
  var year2 = birthday.getUTCFullYear();
  var hour2 = birthday.getUTCHours();
  var ms2 = birthday.getUTCMilliseconds();
  var um1 = birthday.getUTCMinutes();
  var umth = birthday.getUTCMonth();
  var us = birthday.getUTCSeconds();

  document.write(date1 +"<br>");
  document.write(day1 +"<br>");
  document.write(year1 +"<br>");
  document.write(hour1 +"<br>");
  document.write(ms1 +"<br>");
  document.write(m1 +"<br>");
  document.write(mth1 +"<br>");
  document.write(time1 +"<br>");
  document.write(s1 +"<br>");
  document.write(offset +"<br>");
  document.write(date2 +"<br>");
  document.write(day2 +"<br>");
  document.write(year2 +"<br>");
  document.write(hour2 +"<br>");
  document.write(ms2 +"<br>");
  document.write(um1 +"<br>");
  document.write(umth +"<br>");
  document.write(us);
</script>

• Output:

• getDay(): 
  This method will return the day of the week (0 for Sunday and 6 for Saturday) for the specified date according to the local time. 
  
• getFullYear(): It returns the year for the specified date according to local time. 
  
• getHours(): It returns the hour(0-23) for the specified date according to local time. 
  
• getMilliseconds: It returns the milliseconds (0-999) for the specified date according to local time. 
  
• getMinutes(): It returns the minutes (0-59) for the specified date according to local time. 
  
• getMonth(): It returns the month (0-11) for the specified date according to local time. 
  
• getSeconds(): It returns the seconds(0-59) for the specified date according to local time. 
  
• getTime(): It returns the number of milliseconds elapsed since January 01, 1970 00:00:00 UTC. It is negative for time 
  before the given time. 
  
• getTimezoneOffset(): It returns the timezone offset in minutes for current location. 
  
• getUTCDate(): It returns the date of the month (1-31) for the specified date according to universal time. 
  
• getUTCDay(): It returns the day of the week (0-6) for the specified date according to universal time. 
  
• getUTCFullYear(): It returns the year for the specified date according to universal time. 
  
• getUTCHours(): It returns the hours (0-23) for the specified date according to universal time. 
  
• getUTCMilliseconds(): It returns the milliseconds(0-999) for the specified date according to universal time. 
  
• getUTCMinutes(): It returns the minutes (0-59) for the specified date according to universal time. 
  
• getUTCMonth(): It returns the month (0-11) for the specified date according to universal time. 
  
• getUTCSeconds(): It returns the seconds (0-59) for the specified date according to universal time. 
  

It also has some other methods which can be used to convert the date to different formats:

• toDateString(): Returns the “date” portion of the Date as a human-readable string.
• toGMTString(): Returns a string representing the Date based on the GMT (UT) time zone.
• toLocaleFormat(): Converts a date to a string, using a format string.
• toLocalestring(): Returns a string with a locality sensitive representation of this date.
