Dayhaps is a free online calendar platform where users can manage and share their personal and business calendar with others. Beside that you can also follow public calendars on your own calendar with one click. All Haps (events) of public calendars become visible in the calendar of the users and when anything changes in one of the public calendars all followers get notified. Dayhaps is therefore very useful for example for families, sports clubs, theatres, bars and schools. With the clever App for iPhone, iPad and Android devices making appointments has never been so easy. All invitations for appointments can be placed with one click into your own calendar.

It is important to invite your friends and family so you can use Dayhaps in full potential. When you make an appointment with friends or family, just click "Add Hap" (on mobile 'Quick add'). Then go to the tab "invite friends" (on mobile 'Invite') and select the person you want to invite. All invitees receive a message on their phone with an invitation. The receivers can place this event directly into their calendar. If you want to change or reschedule the appointment, all invitees receive a message again! Convenient, right?
