JavaScript Date object
The Date object
Date objects are used to process dates and times.
Create a Date object: new Date().
There are four ways to create a Date object as well:
var d =new Date();
var d =new Date( milliseconds );
var d =new Date( dateString );
var d =new Date( year , month , day , hours , minutes , seconds , milliseconds );
var d =new Date( milliseconds );
var d =new Date( dateString );
var d =new Date( year , month , day , hours , minutes , seconds , milliseconds );
For a fuller date and actual tutorial, refer to the JavaScript Date Object tutorial.
Date object properties
| Property | Describe |
|---|---|
| constructor | Returns a reference to the Date function that created this object. |
| prototype | Gives you the ability to add properties and methods to objects. |
The Date object method
| Method | Describe |
|---|---|
| getDate() | Returns a day of the month (1 to 31) from the Date object. |
| getDay() | Returns a day of the week (0 to 6) from the Date object. |
| getFullYear() | The year is returned in four digits from the Date object. |
| getHours() | Returns the hour of the Date object (0 to 23). |
| getMilliseconds() | Returns the date object's milliseconds (0 to 999). |
| getMinutes() | Returns the minutes of the Date object (0 to 59). |
| getMonth() | Returns the month (0 to 11) from the Date object. |
| getSeconds() | Returns the number of seconds (0 to 59) of the Date object. |
| getTime() | Returns the number of milliseconds from January 1, 1970 to the present. |
| getTimezoneOffset() | Returns the minute difference between local time and Greenwich Mean Time (GMT). |
| getUTCDate() | Returns the day of the month (1 to 31) from the Date object at the time of the world. |
| getUTCDay() | Returns the day of the week (0 to 6) from the Date object based on the world time. |
| getUTCFullYear() | Returns a four-digit year from the Date object based on the world time. |
| getUTCHours() | Depending on the hour (0 to 23) of the Date object is returned when the world is in. |
| getUTCMilliseconds() | Returns the date object in milliseconds (0 to 999) depending on the world. |
| getUTCMinutes() | The minute (0 to 59) of the Date object is returned depending on the world. |
| getUTCMonth() | Returns the month (0 to 11) from the Date object based on the world time. |
| getUTCSeconds() | The second (0 to 59) of the Date object is returned depending on the world. |
| getYear() | Abandoned. Use the getFullYear() method instead. |
| parse() | Returns the number of milliseconds from midnight on January 1, 1970 to the specified date (string). |
| setDate() | Set the day of the month in the Date object (1 to 31). |
| setFullYear() | Sets the year (four digits) in the Date object. |
| setHours() | Set the hours in the Date object (0 to 23). |
| setMilliseconds() | Set the milliseconds (0 to 999) in the Date object. |
| setMinutes() | Set the minutes in the Date object (0 to 59). |
| setMonth() | Set the month in the Date object (0 to 11). |
| setSeconds() | Set the seconds in the Date object (0 to 59). |
| setTime() | The setTime() method sets the Date object in milliseconds. |
| setUTCDate() | Set the day of the month in the Date object (1 to 31) based on the world time. |
| setUTCFullYear() | Set the year (four digits) in the Date object based on the world time. |
| setUTCHours() | Set the hours in the Date object (0 to 23) depending on the world time. |
| setUTCMilliseconds() | Set the milliseconds (0 to 999) in the Date object based on world time. |
| setUTCMinutes() | Set the minutes in the Date object (0 to 59) depending on the world time. |
| setUTCMonth() | Set the month (0 to 11) in the Date object based on the world time. |
| setUTCSeconds() | The setUTCSeconds() method is used to set the second field for a specified time based on World Time (UTC). |
| setYear() | Abandoned. Use the setFullYear() method instead. |
| toDateString() | Converts the date portion of the Date object to a string. |
| toGMTString() | Abandoned. Use the toUTCString() method instead. |
| toISOString() | The date format of the string returned using the ISO standard. |
| toJSON() | Returns the date string in JSON data format. |
| toLocaleDateString() | Convert the date portion of the Date object to a string based on the local time format. |
| toLocaleTimeString() | Convert the time portion of the Date object to a string based on the local time format. |
| toLocaleString() | According to the local time format, the Date object is converted to a string. |
| toString() | Convert the Date object to a string. |
| toTimeString() | Converts the time portion of the Date object to a string. |
| toUTCString() | Depending on the world, the Date object is converted to a string. |
| UTC() | Returns the number of milliseconds from January 1, 1970 to the specified date, depending on the world time. |
| valueOf() | Returns the original value of the Date object. |
