The fourth type combines a measure-like role with a container-like role. Hajj is the example.
Its stated season is Shawwal, Dhu al-Qa'dah and the first 10 days of Dhu al-Hijjah. Two Hajj performances cannot be completed in that year's season, so its time is like a measure.
Yet the rites do not occupy that entire season. The example describes the rites within 9–13 Dhu al-Hijjah, a much smaller span. In this respect, the season is like a container.
These describe different things: the Hajj season and the period occupied by its rites. The point is the two roles of time, not that every named day is a separate obligatory act.
