    /*! Holidays for the Kuala Lumpur stock exchange (Bursa Malaysia).

        Bursa Malaysia observes the federal public holidays gazetted for the

        Federal Territory of Kuala Lumpur, so state-only holidays (for example

        Good Friday in Sabah and Sarawak, or the Harvest Festival in Sabah and

        Labuan) are deliberately not included.

        Holidays with a fixed date:

        <ul>

        <li>Saturdays</li>

        <li>Sundays</li>

        <li>New Year's Day, January 1st</li>

        <li>Federal Territory Day, February 1st</li>

        <li>Labour Day, May 1st</li>

        <li>National Day (Hari Merdeka), August 31st</li>

        <li>Malaysia Day, September 16th (a federal holiday since 2010)</li>

        <li>Christmas Day, December 25th</li>

        </ul>

        Holidays with no fixed rule, tabulated for 2015 to 2027:

        <ul>

        <li>Chinese New Year (two days)</li>

        <li>Thaipusam</li>

        <li>Wesak Day</li>

        <li>Deepavali</li>

        <li>Nuzul Al-Quran</li>

        <li>Hari Raya Aidilfitri (two days)</li>

        <li>Hari Raya Haji</li>

        <li>Awal Muharram</li>

        <li>Maulidur Rasul</li>

        <li>Birthday of the Yang di-Pertuan Agong</li>

        <li>Substitute days granted when a gazetted holiday falls on a Sunday</li>

        <li>One-off federal holidays (royal installations, the 2018 general

            election, the 2017 SEA Games)</li>

        </ul>

        The Islamic, Chinese and Hindu festivals are set each year by

        proclamation rather than by calculation, so they are tabulated from the

        published holiday lists rather than computed. Outside the tabulated

        range only the fixed-date holidays above are returned.

        Holiday dates compiled from the gazetted Malaysian public holiday

        lists published at

        <https://www.officeholidays.com/countries/malaysia>, cross-checked for

        2021-2026 against Google's public Malaysia holiday calendar. They

        should be verified against the trading calendar published by Bursa

        Malaysia at <https://www.bursamalaysia.com/> before being relied upon.
