Alternatively, you can include the days.js file directly in your HTML page:

<script src="days.js"></script>

Usage

To start using days.js, you need to import the library into your JavaScript file:

const days = require('days.js');

Date Manipulation

To perform date manipulation, you can use the addDays, subtractDays, addMonths, and subtractMonths methods:

const currentDate = new Date();
const futureDate = days.addDays(currentDate, 7);
const pastDate = days.subtractDays(currentDate, 3);
const nextMonth = days.addMonths(currentDate, 1);
const previousMonth = days.subtractMonths(currentDate, 1);

Duration Calculation

To calculate the duration between two dates, you can use the getDuration method:

const startDate = new Date(2022, 0, 1);
const endDate = new Date(2022, 0, 31);
const durationInDays = days.getDuration(startDate, endDate, 'days');
const durationInMonths = days.getDuration(startDate, endDate, 'months');
const durationInYears = days.getDuration(startDate, endDate, 'years');

Date Formatting

To format a date, you can use the formatDate method:

const date = new Date();
const formattedDate = days.formatDate(date, 'YYYY-MM-DD');

Parsing and Validation

To parse and validate a date string, you can use the parseDate and isValidDate methods:

const dateStr = '2022-01-01';
const parsedDate = days.parseDate(dateStr);
const isValid = days.isValidDate(parsedDate);

Conclusion

days.js is a powerful JavaScript library that simplifies date and duration manipulation. It offers a wide range of features, including date manipulation, duration calculation, date formatting, and parsing/validation. By using days.js, you can save time and effort when working with dates in your JavaScript projects.
