The league is generally played between March to November in the calendar year and has occasionally had the Super Cup as a curtain raiser to the domestic campaign. Teams play each other on a home and away basis. Two or three teams can be relegated depending on the number of sides participating which has in the past been between 17 and 14 sides. Occasionally no sides would be promoted from the First League, due to reserve teams winning the championships. Reserve clubs are not allowed to feature in the top flight but can play at any level up to First League. On these occasions, clubs can be relegated without any promoted sides making the next campaign feature less sides than before.
