Subscribing to my Mac's iCal Calendar

Subscribing to my Mac's iCal Calendar

Hello,
 
I'd like to use Zoho Calendar as my primary calendar.
 
I'd like however to have any entry that I add to My Mac's iCal calendar sync with Zoho Calendar.
 
Is this possible?
 
Or do I have to do a one time import of my iCal Calenar into Zoho Calendar and continue to use only Zoho calendar from that point on?
 
Thanks
 
Armand
