Emre Alper, S. Boragan Aruoba] When holiday variation is present so that the dates of certain holidays change from year to year, the relatively automatic seasonal adjustment procedures may fail to extract the seasonal component from a series since the holiday effects are not confined to that component. Turkey, a predominantly Muslim country, constitutes a good example of moving holidays since the official calendar is Gregorian, based on the cycles of the Earth around the sun, while significant Islamic holidays are tied to the Hegirian calendar, based on the lunar cycles. One finds significant deterministic seasonality remains in the conventionally de-seasonalized time series and removing the effects of religious seasonality using a very simple method improves the qualities of the de-seasonalized component. ©2011 Walter de Gruyter GmbH & Co.
