In the Change Working Time dialogue box under Create New Calendar there is a line that reads Working time for ... date
it then normally shows the start and finish times for the day.
In this case it is only showing the morning times and not the afternoon session.



Working OK in Project 2010.

TIA

Do you have SP-1 for Project 2013 installed? Have all Tuesdays been modified? You have Monday selected in the top screen capture and August 5 is a Tuesday.

SP-1 installed and all dates were correctly entered.
Out of the blue it appears to have fixed itself.

Project rarely fixes it self "out of the blue". There may be been an update installed that fixed the issue. None-the-less glad it is now working as expected.
