Quick Start

Once installed, creating and formatting dates is straightforward:

const now = dayjs();
console.log(now.format()); // "2024-06-24T10:30:00+03:00"

const parsed = dayjs('2024-01-15');
console.log(parsed.format('YYYY-MM-DD')); // "2024-01-15"

const manipulated = dayjs().add(7, 'day');
console.log(manipulated.format('dddd, MMMM D, YYYY'));
