<div>= iCalendar implementations = <br />
<br />
In the development of [[hcalendar|hCalendar]] and proxies like X2V, we have discovered various behaviors and quirks of RFC 2445 iCalendar implementations.<br />
<br />
This page is here for keeping track of them.<br />

==== Importing of VEvents ====<br />
<br />
Requires <code>UID</code>, <code>DTSTAMP</code>, and <code>METHOD</code><br />
<br />
If any of the three is not present, returns this message:<br />
<br />
<pre><br />
This error can appear if you have attempted to save a recurring Lunar appointment in iCalendar format.<br />
To avoid this error, set the appointment option to Gregorian instead of Lunar.<br />
</pre><br />
<br />
After some testing, this seems to be the generic message to indicate a problem with event import.<br />
<br />
No such restriction is placed on [http://www.imc.org/pdi/vcal-10.txt iCal 1.0] events. So, if <code>VERSION:1.0</code> is output instead of <code>VERSION:2.0</code>, the only required field is <code>DTSTART</code>. <br />
Note that <code>VERSION</code> property may be omitted. In this case, value inferred as <code>1.0</code>.<br />
