The house of representatives uses five calendars to schedule bills, yet the schedule is often ignored. what is the purpose of special procedures to bring bills to the floor?

The purpose of special special procedures do bring fills to the floor is to allow the House to set aside predictable periods of time when it may consider various categories of proposed legislation.

This happens because the Five house calendars are not calendars in the traditional sense, thus if a measure is listed on a calendar there is no guarantee that it will be considered on the House floor on that date.

A combination of policy, political and procedural factors ultimately lead to the choice of measures on the calendar that the leadership will schedule for consideration as well as its order.
