In some configurations of the partner portal - Occurrences are allowed to have names and descriptions.

Sometimes you may have a volunteer opportunity that needs volunteers broken into separate shifts and/or positions.  Rather than using a Volunteer Event, and separate Volunteer Opportunities (each with one or more occurrences),  you could create a single volunteer opportunity, and for each 'shift' or 'position' volunteers are needed for, you can create a separate occurrence record and give each occurrence an "Occurrence Name" (Such as "Shift 1" "Registration" or "Cleanup Crew".   You can also optionally add a short description of this shift or position that will appear as part of the occurrence information

As an example, we have created a volunteer opportunity called Picnic in the Park, and put a general description of the picnic in the volunteer opportunity description.

We need volunteers for three different jobs at the picnic:

• Check-In station. from 8:30 - 1:30
• Lunch Distribution from 10:30 - 2:30 pm
• Valet Parking from 11 am - 1 pm

So we'll create three occurrences for those three times the same day, and use the Occurrence Name field to identify the 'role' and the Occurrence Description to give volunteers a better idea of what they'll do in that role.
