const getWeek = (date) => {
const janFirst = new Date(date.getFullYear(), 0, 1);
// Source: https://stackoverflow.com/a/27125580/3307678
return Math.ceil((((date.getTime() - janFirst.getTime()) / 86400000) + janFirst.getDay() + 1) / 7);
}
const isSameWeek = (dateA, dateB) => {
return getWeek(dateA) === getWeek(dateB);
}
const dateA = new Date('2021-09-20')
const dateB = new Date('2021-09-24')
const dateC = new Date('2021-09-27')
console.log(isSameWeek(dateA, dateB));
console.log(isSameWeek(dateA, dateC));A momentjs one-liner:
moment().format('W')
