Here's the code that I have right now:
const moment = require('moment')
const m = moment
const currDay = m().format('D')
const dayOfWeek = m().format('dddd')
const daysInMonth = m().daysInMonth()
const startOfMonth = moment().startOf('month').format('YYYY-MM-DD hh:mm');
const endOfMonth = moment().endOf('month').format('YYYY-MM-DD hh:mm');
I need to create a calendar row where the first item would be the todays date, and the rest of the calendar items would be the whatever amount of days are left depending on the current month so I could render each day in between in my HTML with Vue.
Example: Wed 8, Thu 9, Fri 10 ... Fri 31.
I think the OP is tripped up on the common mistake of formatting prematurely. format is good to see an intermediate result, but doing so produces a string that's no good for additional calculation.
Try to handle date objects only. Convert to strings only when you must: (a) presenting to a human reader, or (b) serializing for storage or transmission.
Working without formatting...
const daysRemainingThisMonth = moment().endOf('month').diff(moment(), 'days');
console.log(`There are ${daysRemainingThisMonth} days remaining this month`)<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.29.1/moment.min.js"></script>Just as a POJS equivalent, if you have a function to return the last day of the month, you can use that and just get the difference between the two dates, e.g.
function getMonthEnd(date = new Date()) {
return new Date(date.getFullYear(), date.getMonth() + 1, 0);
}
function getMonthDaysLeft(date = new Date()) {
return getMonthEnd(date).getDate() - date.getDate();
}
let d = new Date();
console.log(`There are ${getMonthDaysLeft(d)} days left in ${d.toLocaleString('en',{month:'long'})}.`);To get a list/array of the days remaining, just loop over a date, adding 1 day at a time, and write the dates in the required format into the list:
function getMonthDaysLeftAsList(date = new Date()) {
let d = new Date(+date);
// Formatter
let f = new Intl.DateTimeFormat('en',{
day: 'numeric',
month: 'short'
});
let m = d.getMonth();
let dayList = [];
while (d.getMonth() == m) {
dayList.push(f.format(d));
d.setDate(d.getDate() + 1);
}
return dayList;
}
console.log(getMonthDaysLeftAsList());
