Hello,

We have tested the website on different browsers (Android 2.3) and could not find any problems. What browsers are you using?

Thank you

I use an HTC Explorer (Android 2.3.5) and the standard browser. I tried the UC browser with no luck. The calendar does not show. The mobile phone is 4 years old. So, this might not be an issue for most users who will probably have modern smartphones.

I am looking into this situation.

Thank you.
