I was thinking.. what about allowing big time spans, like: from

ISO 8601 specifies how to code time intervals (and durations) in
several ways: start and end date/time, start date/time and duration,
duration and end date/time, or duration only – the separtor alwas is
a forward slash ‘/’, replacable by a double hyphen ‘--’ if
necessary.
If HTML was to support this it should do so in compatibility with
ISO
8601.
Setting a date range limitation is already possible according to the
current version of HTML5 drafts, just not as an ISO 8601 range
notation (which nobody uses outside laboratories and which requires
parsing the limits) but with min and max attributes, e.g.
<input type="date" min="2011-04-01" max="2011-06-30">

This is supported both by Opera (in its calendar widget) and by
Chrome (in its somewhat odd widget that lets you scroll through
dates,
one date at a time, but I think that's meant to be allowed as
conforming).
That is perfect for 1 date scope. What if I have a meeting to schedule
in a month (eg. March) and (according to other meeting attendees) the
meeting can only happen from 10-15, 19, 20-28 and 30. Do I have to make
a data-list with every possible day? What if I would like to set a
future event that cannot happen on weekends?
