Module: Holidays::Definition::CustomMethods::TR

Defined in:

lib/holidays/definition/custom_methods/tr.rb

Overview

tr custom holiday calculations.

Ramazan Bayramı is 1 Shawwal and Kurban Bayramı is 10 Dhul-Hijjah of the Hijri calendar. Both are derived from the arithmetic Islamic calendar (Holidays::DateCalculator::HijriDate). The civil holidays are proclaimed by Türkiye's Diyanet and in most years so far have landed a day (2016 Ramazan Bayramı, two days) before the arithmetic result; DIYANET_OVERRIDES pins those years to the proclaimed date. Years with no entry fall back to the calculation. See definitions#377.
