Using Moment js It is very easy to find the number of days in a given month.

Suppose your date format is 2019-03-30 you want to know the number of days in 2019-03

const moment = require('moment')

moment('2019-03', 'YYYY-MM').daysInMonth()

For Number of days in a given year, Check if the given year is a leap year or not, if it is a leap year, number of days = 366, else 365.

let isLeapYear = moment([2019]).isLeapYear()

let numOfDaysInYear = 365
if(isLeapYear){
  numOfDayInYear = 366
}

Use new Date as like below

function getNumOfDays(y, m) {
    return new Date(y, m, 0).getDate();
}
