Google Calendar makes it easy to schedule events and can automatically send invitations and track RSVPs through your email.

Sync the built-in calendar on popular mobile phones such as Android and iPhone with your Google Calendar or access your calendar from any device with a web browser.

The Google Calendar app for Chrome lets you view your schedule and respond to invites, even when you don’t have an internet connection. Your calendar and RSVPs will be synced the next time you connect to the internet.

If someone else helps you manage your calendar, you can make this even easier by delegating access to that person. This allows another user to create events, respond to invites and manage your schedule.

Google Calendar makes it easy to work with people in other timezones. Features like timezone conversion makes sure your calendar time zone follows you when you travel and customizable working hours reminds your colleagues not to schedule meetings in the middle of the night.

If you use a desktop calendar application, such as Microsoft Outlook®, Apple iCal or Mozilla Sunbird, you can keep it in sync with Google Calendar automatically.

You can add a widget to the side of your calendar that can show current availability for the people you work with most. This way you know who’s available for a quick call or chat and who’s tied up in a meeting.

Google Calendar is designed for security and reliability with features like encrypted connections to Google’s servers, simultaneous replicated storage for your calendar appointments, built-in disaster recovery and fine-grained sharing, which lets you share your calendar with people in and out of your organization.

Get custom reminders in your inbox or on your mobile phone with all the details about your upcoming meetings and events, right when you need them.
