There is NO 30/04/17 and other dates!

Hello!

I love your product and from time to time use it for plan dates for football matches. Thank you very much. For me it is very comfortable. But today i realise that there is no 29 and 30 of april 2017. When i choose this dates in gantt diagram my date automatically changes to 1 of May 2017.

I think: Okay. This time i try to use dates from 2016. But there is no dates 30 of April and 1 of May 2016!!!

I think: Okay. I try to use dates from 2015. But there is no dates 2 and 3 of May 2015!!!

Please say how to fix it, because i didn’t find more suitable tool for my needs.

Thank you for you time.

You have [non-working] weekend days in your project. Tasks can’t be scheduled on non-working days. If you try to set task start on non-working day, it will be set on the first later working day. Change your project calendar settings, and either remove weekends or choose the option to count them as workign days.

For the record, the dates shown on the screenshot are not from May, because week 27-28 is the end of June/beginning of July.

How to change calendar settings? I have the same problem.
