In the countries that observe this holiday, 26 December is commonly referred to both as Boxing Day and as St. Stephen's Day, no matter what day of the week it occurs.[7] However, in some countries, holidays falling on Saturday or Sunday are observed on the next weekday. Traditionally, Boxing Day could not be on a Sunday, that day being the officially recognized day of worship, so it was the next working day of the week following Christmas Day, (i.e. any day from Monday to Saturday).
In recent times, this tradition has been either forgotten or ignored. Most, but not all, calendars and media outlets consider 26 December to be Boxing Day even when it falls on a Sunday.
