Calendar Rail — shortcut for Gmail

Add a private Calendar shortcut to Gmail’s left navigation. Free, with no ads or tracking.

Add a Calendar button below Mail, Chat and Meet in Gmail’s left navigation. Select it to expand Gmail’s built-in Calendar companion across the center workspace, without opening a new tab. Select Mail, Chat or Meet to return. This uses the Calendar companion’s available views and features, rather than the full standalone Calendar website. Gmail handles sign-in and account selection. Gmail’s right side panel must be shown, and your organization may restrict Calendar. The original outline icon follows Gmail’s text color and supports narrow navigation. Unknown layouts hide the button or show an opening error. Refresh Gmail after installation or updates. Free. No ads, subscriptions, analytics, backend, account connection or persistent storage. No reading of messages, attachments, contacts, account addresses or calendar event contents. No network API calls or developer servers. Your browser asks to read and change data on mail.google.com. That access is necessary to add the button, activate Gmail’s existing Calendar control and resize its panel. No Calendar host access or extra extension API permissions are requested. This extension is an independent product and is not affiliated with, endorsed by, or sponsored by Google or any Google product.
