+ * Properties that apply to the entire calendar, as well as one or more blocks
+ * of multiple lines that each define a Calendar Component such as an event,
+ * journal entry, alarm, or one of several other types. Here is a simple example
+ * of an iCalendar object with a single calendar containing a single Calendar
+ * Component, a "Bastille Day Party" event starting at 5pm on July 14, 1997, and
+ * ending at 4am the following morning:[10]

+
+The UID field distributes updates when a scheduled event changes. When the event
+is first generated a globally unique identifier is created. If a later event is
+distributed with the same UID, it replaces the original one. An example UID
+might be Y2007S2C131M5@example.edu, for the 5th meeting of class 131 in semester
+2 at a hypothetical college. Email-style UIDs are now considered bad practice,
+with a UUID recommended instead.[11]
+
+The most common representation of date and time is a tz timestamp such as
+20010911T124640Z with the format <year (4 digits)><month (2)><day (2)>T<hour
+(2)><minute (2)><second (2)>Z for a total fixed length of 16 characters. Z
+indicates the use of UTC (referring to its Zulu time zone).[12] When used in
+DTSTART and DTEND properties, start times are inclusive while end times are not.
+This allows an event's end time to be the same as a consecutive event's start
+without those events overlapping and potentially creating (false) scheduling
+conflicts.[13]
