Date Time API

Introduction

The Date Time API is a comprehensive library designed to simplify date and time manipulation in JavaScript. It provides a wide range of utilities for parsing, validating and formatting dates and times, making it easier for developers to handle date-time operations in their applications.

Usage

import * as dateTime from "@atlassian/date-time";

// Parse a date string
const date = dateTime.parse("2024-01-01");
console.log(date); // Outputs: "Mon Jan 01 2024 00:00:00 GMT+0000 (Coordinated Universal Time)"

// Get date pattern
const pattern = dateTime.getDatePattern("en-US");
console.log(pattern); // Outputs: "mm/dd/yyyy"

// Validate a date string
const isValid = dateTime.validate("2024-01-01");
console.log(isValid); // Outputs: true

// Format a plain date
const plainDate = dateTime.formatPlainDate(new Date());
console.log(plainDate); // Outputs: "2024-01-01"

// Format a plain time
const plainTime = dateTime.formatPlainTime(new Date());
console.log(plainTime); // Outputs: "12:00:00"

// Format a plain date-time
const plainDateTime = dateTime.formatPlainDateTime(new Date());
console.log(plainDateTime); // Outputs: "2024-01-01T12:00:00"

// Format a numeric date
const numericDate = dateTime.formatNumericDate(new Date(), "en-US");
console.log(numericDate); // Outputs: "1/1/2024"

// Format a date
const formattedDate = dateTime.formatDate(new Date(), "en-US");
console.log(formattedDate); // Outputs: "Jan 1, 2024"

// Format a time
const formattedTime = dateTime.formatTime(new Date(), "en-US");
console.log(formattedTime); // Outputs: "12:00:00 PM"

// Format a date-time
const formattedDateTime = dateTime.formatDateTime(new Date(), "en-US");
console.log(formattedDateTime); // Outputs: "Jan 1, 2024, 12:00:00 PM"

// Format a date-time with options
const formattedDateTimeWithOptions = dateTime.formatDateTimeByOptions({ second: undefined }, new Date(), "en-US");
console.log(formattedDateTimeWithOptions); // Outputs: "Jan 1, 2024, 12:00 PM"

// Format a duration
const duration = dateTime.formatDuration(new Date(2024, 0, 1), new Date(2024, 0, 2), "en-US");
console.log(duration); // Outputs: "1 day 1 hour 1 minute 1 second"

// Format a duration with custom options
const durationWithOptions = dateTime.formatDurationByOptions({ unitDisplay: "narrow" }, new Date(2024, 0, 1), new Date(2024, 0, 2), "en-US");
console.log(durationWithOptions); // Outputs: "1d 1h 1m 1s"
