Provides a Joi rule to validate IANA timezone strings (eg. Europe/London, America/New_York, Etc/GMT-8) using luxon.

Joi-tz supports and is tested against Joi 16.x or higher.

This project is forked from joi-timezone (unmaintained). That project remains functional for Joi 9.x-15.x.

npm: npm install joi-tz

yarn: yarn add joi-tz

import BaseJoi from 'joi';
import JoiTimezone from 'joi-tz';

const Joi = BaseJoi.extend(JoiTimezone);

Joi.timezone().validate('Australia/Darwin');
// returns {value: 'Australia/Darwin'}

This library is tested for compatibility, and contains peer dependencies with the following versions.
