Note that holidays falling on a sunday maybe observed on the following Monday.
This depends on formal announcements by the government, which only happens close
to the date of the holiday.
When it appears inappropriate for a public holiday listed in Article 1 to be observed because
it coincides with a Sunday, it shall be postponed to the following working day, which shall
accordingly be considered a public holiday and observed as such.
