Calendar software to organize your schedule


Calendar software to organize your schedule

A power calendar for your important appointments

In business environments, every activity is related to a date and time.
Successful business often means “fast moving”. In modern software development, for instance, there is no chance to survive global competition without applying agile methods.

In order to be successful, teams need to be perfectly organized. A key element to be organized is a powerful insight into milestones, deadlines and upcoming events, whatever they may be.
To get an accurate, immediate and complete overview, you need a “power calendar” that is always updated, containing all events that may be relevant.

A calendar is supposed to show all relevant actions scheduled on a certain date or within a period at one glance .
VNCcalendar is based upon state of the art frontend technologies, presenting your events on any device, including mobile Apps. VNCcalendar receives its datafeed (your dates and meetings) via the powerful VNCaxf Restful API.

As a consequence, VNCcalendar is fed from various backend information systems such as VNCmail, VNCproject, VNCtalk and others – integrated as needed.

Here again we follow the strategy to have a single point of access to all relevant data.

VNCcalendar is fed from various backend information systems


VNClagoon is an unmatched unified suite of enterprise communication and collaboration solutions.

Various Sources

Connect VNCcalendar with other VNClagoon applications, like for example VNCproject or VNCmail. VNCcalendar can be fed from various backend systems, so you can add appointments from emails, tickets or any other connected source you like.


Topic, location, attendees, date and time – sure. VNCcalendar offers all basic information for standard appointments like any other calendar. But VNCcalendar allows you also to add a list of required equipment. Furthermore, you can add the description as plain text or HTML for more structured information.

Rich Functions

Of course VNCcalendar provides every useful feature you already are familiar with, like different settings for the calendar view (day, work week, week, month). Each appointment has various options to manage details, such as topic, date, time with time-zone, duration, location, participants, recurring events, reminder, attachments and equipment like whiteboards or flipcharts.

VNClagoon Integrations

Through the integration with different VNClagoon products you can also add appointments from emails you received, tickets you created or are assigned to.

Notifications & Reminders

Of course VNCcalendar will remind you with notifications. Here, you can set different notification patterns for every single appointment.

Multiple Calendars

Creating and displaying several calendars and sub-calendars in different colors, sharing your calendar with other users (entries are visible or private). All these features are implemented in a tidy and convenient design and can be used intuitively.

VNCcalendar Web Client

Fast access wherever you are

The VNCcalendar web client offers all features a calendar needs. You can create and manage the details of your appointments, share them with other users (private or public) and invite additional persons to your meetings.

Since VNCcalendar can be integrated with VNCmail you need only one browser tab to manage your emails and appointments.

Each appointment has various options to manage details, such as topic, date, time with time-zone, duration, location, participants, recurring events, reminder, attachments and equipment like whiteboards or flipcharts.
