For that it is possible to make the calendar field become the setting to specify entry start publishing date or entry stop publishing date. Also recurring dates like daily, weekly, monthly and yearly dates are possible.
The date field features a popup calendar in the entry add/edit form that lets users easily select a date. In addition, there are sliders that allow you to choose a specific time as well.
A calendar listing shows you all dates entered in your events site in a specific calendar view.
Schema.org is supported.
This application is available within a SobiPro club membership among with many other club extensions for SobiPro.
Note: Installs using the SobiPro installer
Furthermore you can use this data in several ways in your template. This is a great addon to SobiPro and I find myself using it for most of my SobiPro Sections.
One thing that people should know if you understand the SobiPro template system. You can use this field to its full advantage and not just to use it to show dates, but do other cool things with it. My point being, learn the template system. It is not that hard and very easy to learn. Once you learn it you will be building SobiPro templates like a champ and getting full use of your SobiPro installation as a CCK or Directory!
