<p>Making an appointment means</p>
<ul>
<li>Add date, time and title of the appointment to the Android-Calendar</li>
<li>In Android-Calendar-Detailview use Send/Share (from menu or toolbar)</li>
<li>Select "CalEF" as share destination (to convert to human readable text)</li>
<li>Select the final Send/Share destination (clipboard, sms, mail, ...)</li>
</ul>
<p>Usually calendar entries are shared in a human-unreadable technical format
"ICS" (or "VCS") that calendar programs can read.</p>
<p>CalEF receives the technical format and re-sends/re-shares it-s content as human readable text.</p>
<p>Date/Time is formatted according to current language/locale.</p>
<p>CalEF can also process "ics" (or "vcs") files (i.e. from a calendar backup).</p>
