Daypilot trial expires at one day

Asked by Jorma Hytonen

Yesterday I download, install and try Daypilot Pro JavaScript (Version 8.2.2200 (May 25, 2016)) and build Hotel Booking system. (

I can create Rooms and Reservations, but after ONE DAY reservations dot not show in grid. Rooms are ok, but reservations NOT. Reservations are in mysql database but not shown in the grid.

Why there is the time limit of one day?
I can't show demo to my customer, if trial version expires at one day.

There is no built-in expiration mechanism that would cripple displaying the data. It looks like there might be a problem/bug.

I assume you are using the sample project from but you have replaced the DayPilot JS (daypilot-all.min.js) with the latest version from

1. If you keep the original version of daypilot-all.min.js that was included in the tutorial, does it work?
2. If you inspect the AJAX calls using browser developer tools, do you see the correct data set being returned by backend_events.php?
