Syntax
dateObj.getDay()
Return value
An integer number, between 0 and 6, corresponding to the day of the week for the given date, according to local time: 0 for Sunday, 1 for Monday, 2 for Tuesday, and so on.
Examples
Using getDay()
The second statement below assigns the value 1 to weekday
, based on the value of the Date
object Xmas95
. December 25, 1995, is a Monday.
var Xmas95 = new Date('December 25, 1995 23:15:30'); var weekday = Xmas95.getDay(); console.log(weekday); // 1
Note: If needed, the full name of a day ("Monday"
for example) can be obtained by using Intl.DateTimeFormat
with an options
parameter. Using this method, the internationalization is made easier:
var options = { weekday: 'long'}; console.log(new Intl.DateTimeFormat('en-US', options).format(Xmas95)); // Monday console.log(new Intl.DateTimeFormat('de-DE', options).format(Xmas95)); // Montag
