Free Online Office Calendar

Even Google Calendar won’t give you so many features for free as Bitrix24. There are personal calendars, shared group or office calendars, repeating events, invitations and meeting bookings. And that’s not all.

Looking for free online office calendar? You will love our cloud software that has so generous free plan. First of all, each user of the account can have multiple calendars, if necessary. It can be private, for a workgroup or company usage. Event planner automatically sends invitations to all potential participants. If the event repeats often or scheduled with a particular frequency, create a recurring event. Set time for notifications, mark participants’ availability and go to the meeting room of your choosing.


Bitrix24.Calendar can be synchronized with external calendars such as Google Calendar or Outlook. Each workgroup can have a calendar and schedule events for themselves. All of the events from private and common calendars can be displayed on a single grip. Also, you can easily add timetables of colleagues or groups to your favourites and follow them. Access rights for every calendar are available and adjustable.


And a special thing is, that Bitrix24 has a free in-build CRM inside, so you can attach meetings with your leads or other CRM elements to your calendars. As well as tasks. Yep, Bitrix24 has tools for task management too. To be honest, our piece of software is a masterpiece with versatile purposes, and you can run your entire company with it, in the office or even remotely.


There are free tools for intranet communication, project, document and task management, CRM, the online store with a website builder, and contact center. But that’s very general. Why won’t you go and see it on your own? Free plan on Bitrix24 is always available. And if you want, go further and try a free 30-days trial of premium features.
