Google Calendar vs Zoho Calendar

Google Calendar
Google Calendar is a free time-management web application offered by Google. The Ajax-driven interface enables users to view, add, and drag-and-drop events from one date to another without reloading the page. It supports view modes such as weekly, monthly, and agenda. Google Calendar allows multiple calendars to be created and shown in the same view. Each can be shared, either read-only or with full edit control, and either with specified people or with everyone (public calendars).
Zoho Calendar
Zoho Calendar allows you schedule, manage and track your meetings and events. Groups and teams can easily share their planned activities so everyone is on the same page, and with Zoho Calendar's powerful sharing controls, you can share only what you want to. In addition, Zoho Calendar also gives you an unified view across many Zoho Apps, from Zoho CRM appointments to Zoho Projects deadlines.

2010 - Zoho Calendar - the best online calendar in the market to fight Google Calendar

Zoho Calendar
Today, Zoho updated its Zoho Calendar and released it out of beta. And Zoho's chief evangelist, Raju Vegesna, called this service the best online calendar in the market. Given that he is a modest person, and Zoho never promoted its products with loud statements, perhaps, this is true. At least, this service is no worse than Google Calendar, simply because it's a complete clone of Google Calendar. Zoho Calendar allows to create multiple calendars, share them (with different access levels), set reminders (by email, RSS), send invitations, embed public calendars on your site / blog. It has a plugin for Outlook (for synchronization), mobile version and supports offline access with Google Gears. Calendars can be synchronized with external services via ICAL protocol. And of course, Zoho Calendar is tightly integrated to other Zoho services (CRM, Projects, Planner, Mail, Chat).
