The JavaScript Date object is used to create objects that store all the temporal values of a point in time, from its year to its millisecond. The methods of this object provide a great variety of ways to set and obtain values from that point in time.
Constructors
You can create a new Date object using the constructor of the Date object in four different ways:
var myDate = new Date() /* Creates a new Date object specifying its point in time as the one of its creation. */
var myDate = new Date(milliseconds) /* Creates a new Date object specifying its point in time in milliseconds passed since January 1st 1970. */
var myDate = new Date(dateString) /* Creates a new Date object specifying its point in time by the information in a string. There are various possible patterns for the dateString string. */
var myDate = new Date(year, month, day of the month, hours, minutes, seconds, milliseconds) /* Creates a new Date Object specifying the temporal values of its point in time. All the parameters are numbers and the month must be a number from 0 to 11, zero being January and eleven being December. Only the year, the month, and the day of the month are required; the rest are optional. */
var myDate = new Date(milliseconds) /* Creates a new Date object specifying its point in time in milliseconds passed since January 1st 1970. */
var myDate = new Date(dateString) /* Creates a new Date object specifying its point in time by the information in a string. There are various possible patterns for the dateString string. */
var myDate = new Date(year, month, day of the month, hours, minutes, seconds, milliseconds) /* Creates a new Date Object specifying the temporal values of its point in time. All the parameters are numbers and the month must be a number from 0 to 11, zero being January and eleven being December. Only the year, the month, and the day of the month are required; the rest are optional. */
Methods
| getDate | Returns the day of the month of the stored point in time in an integer number from 1 to 31. |
| getDay | Returns the day of the week of the stored point in time in a number from 0 to 6, zero being Sunday and six being Saturday. |
| getFullYear | Returns the year of the stored point in time with all its digits. |
| getHours | Returns the hour of the stored point in time in a number from 0 to 23. |
| getMilliseconds | Returns the milliseconds since the last second of the stored point in time in a number from 0 to 999. |
| getMinutes | Returns the minutes of the stored point in time in a number from 0 to 59. |
| getMonth | Returns the month of the stored point in time in a number from 0 to 11, zero being January and eleven being December. |
| getSeconds | Returns the seconds of the stored point in time in a number from 0 to 59. |
| getTime | Returns the quantity of milliseconds passed since January 1st 1970 until the stored point in time. |
| getTimezoneOffset | Returns the difference in minutes between the universal time and the time in the host computer. |
| getUTCDate | Returns the day of the month of the stored point in time according to universal time in a number from 1 to 31. |
| getUTCDay | Returns the day of the week of the stored point in time according to universal time in a number from 0 to 6, zero being Sunday and six being Saturday. |
| getUTCFullYear | Returns the year of the stored point in time with all its digits according to universal time. |
| getUTCHours | Returns the hour of the stored point in time according to universal time in a number from 0 to 23. |
