Events are calendar entries which can be used to organize appointments, or group events in real life (set a location) or virtually (add a link to your meeting)
Events also have the added ability of inviting contact and sending them an invite email. This is ideal for contacts you know
Alternatively for wider distribution, event can be made shareable via a link. Share to your social media followers, whatsapp group or email list. More details how to share here.
