Module calendar 

Clause 21 codecs for BACnetCalendarEntry and BACnetDateRange.

A calendar entry is the element of the Calendar object’s Date_List (Clause 12.9) and the inline period of a Schedule BACnetSpecialEvent (Clause 12.24). It is a CHOICE whose alternatives carry their own context tags:

Alternative	Tag	Encoding
date	[0]	primitive, the four Date octets
date-range	[1]	opening/closing pair around a BACnetDateRange
weekNDay	[2]	primitive, the three BACnetWeekNDay octets

BACnetDateRange is a SEQUENCE of two untagged Dates, so each is application-tagged: start date, then end date. Unframed, as a Schedule’s Effective_Period carries it, that pair is the whole encoding. A BACnetLIST of calendar entries is the plain concatenation of its elements.
