getMonth in javascript gives previous month
I am using a datepicker which gives a date in the format Sun Jul 7 00:00:00 EDT 2013. Even though the month says July, if I do a getMonth, it gives me the previous month.
var d1 = new Date("Sun Jul 7 00:00:00 EDT 2013");
d1.getMonth());//gives 6 instead of 7
What am I doing wrong?
Solution 1:
Because getmonth() start from 0. You may want to have d1.getMonth() + 1
to achieve what you want.
Solution 2:
getMonth()
function is zero indexed based. You need to do d1.getMonth() + 1
Recently I used Moment.js library and never looked back. Try it!
Solution 3:
Presuming you use your variable
var d1 = new Date("Sun Jul 7 00:00:00 EDT 2013");
Month requires a +1 to be accurate, it starts counting at 0
d1.getMonth() + 1 // month
In contrast.... these methods DON'T need a plus 1
d1.getSeconds() // seconds
d1.getMinutes() // minutes
d1.getDate() // date
And notice it is .getDate()
NOT .getDay()
d1.getDay() // day of the week as a
Hope this helps
I suspect these methods lack consistency for historical reasons
Solution 4:
const d = new Date();
const time = d.toLocaleString('en-US', { hour: 'numeric', minute: 'numeric', second:'numeric', hour12: true });
const date = d.toLocaleString('en-US', { day: 'numeric', month: 'numeric', year:'numeric' });
OR
const full_date = new Date().toLocaleDateString(); //Date String
const full_time = new Date().toLocaleTimeString(); // Time String
Output
Date = 8/13/2020
Time = 12:06:13 AM
Solution 5:
Yes, this seems to have been a boneheaded decision on someone's part to make the month zero-indexed while the year and day are not. Here's a little function I use to convert a date into the format expected for the field...
const now = new Date()
const month = (date) => {
const m = date.getMonth() + 1;
if (m.toString().length === 1) {
return `0${m}`;
} else {
return m;
}
};
const day = (date) => {
const d = date.getDate();
if (d.toString().length === 1) {
return `0${d}`;
} else {
return d;
}
};
const formattedDate = `${now.getFullYear()}-${month(now)}-${day(now)}`
