Come ottenere l'ultimo giorno del mese

Question

Come posso ottenere l'ultimo giorno del mese con la data e l'ora 11:59:59 PM?

Answer 1

Questo vi darà ultimo giorno del mese in corso.

var t= new Date(); 
alert(new Date(t.getFullYear(), t.getMonth() + 1, 0, 23, 59, 59)); 

Answer 2

function LastDayOfMonth(Year, Month) { 
    return new Date((new Date(Year, Month,1))-1); 
} 

Esempio:

> LastDayOfMonth(2009, 11) 
Mon Nov 30 2009 23:59:59 GMT+0100 (CET) 

Answer 3

Calendar cal = Calendar.getInstance(); 
cal.set(Calendar.DATE, cal.getActualMaximum(Calendar.DATE)); 

Date lastDayOfMonth = cal.getTime(); 

Answer 4

var d = new Date(); 
m = d.getMonth(); //current month 
y = d.getFullYear(); //current year 
alert(new Date(y,m,1)); //this is first day of current month 
alert(new Date(y,m+1,0)); //this is last day of current month 

Answer 5

var d = new Date(); 
console.log(d); 
d.setMonth(d.getMonth() + 1); // set month as next month 
console.log(d); 
d.setDate(0); // get the last day of previous month 
console.log(d); 

Qui viene emesso dal codice di cui sopra:
gio 3 ottobre 2013 11:34:59 GMT + 0100 (GMT Daylight Time)
Sun 3 Novembre 2013 11 : 34: 59 GMT + 0000 (GMT standard Time)
gio 31 ottobre, 2013 11:34:59 GMT + 0000 (GMT standard Time)

Answer 7

var month = 1; // 1 for January 
var d = new Date(2015, month, 0); 
console.log(d); // last day in January 

Answer 8

A volte tutto quello che hai è una versione di testo del mese in corso, vale a dire: aprile 2017.

//first and last of the current month 
var current_month = "April 2017"; 
var arrMonth = current_month.split(" "); 
var first_day = new Date(arrMonth[0] + " 1 " + arrMonth[1]); 

//even though I already have the values, I'm using date functions to get year and month 
//because month is zero-based 
var last_day = new Date(first_day.getFullYear(), first_day.getMonth() + 1, 0, 23, 59, 59); 

//use moment,js to format  
var start = moment(first_day).format("YYYY-MM-DD"); 
var end = moment(last_day).format("YYYY-MM-DD");
