An online calendar that you can subscribe to and receive updated events whenever the iCal owner updates the calendar, as opposed to importing an ICS file, which provides only a static snapshot of the calendar, and doesn't update.
Spletni koledar, na katerega se lahko naročite in prejemate posodobljene dogodke vsakič, ko lastnik koledarja iCal posodobi koledar, v nasprotju z uvozom datoteke ICS, ki omogoča samo statični pregled koledarja in ga ne posodablja.
