* Mauritius became independent in 1968, but the earliest accessible version of the Public
Holidays Act is the one consolidated in 1991. The most recent update to the holiday
schedule reflected in that version dates back to 1987. Therefore, 1988 is being used
as the starting year.
* [Ougadi](https://en.wikipedia.org/wiki/Ugadi) is another name for the Telugu holiday,
Ugadi, which is celebrated on the same day as Gudi Padwa. Therefore, reusing Gudi Padwa
for adding Ougadi.
