Days of working time in Israel are Sunday through Thursday (for a five-day workweek), or Friday (for a six-day workweek). In observance of Shabbat, in places where Friday is a work day and the majority of population is Jewish, Friday is a "short day", usually lasting till 14:00 in the winter, or 16:00 in the summer. Several proposals have been raised to adjust the work week with the majority of the world, and make Sunday a non-working day, while extending working time of other days or replacing Friday with Sunday as a work day.

Friday is considered what?
short day
