Project 2010 – greying out non-working days on Gantt Chart

If non-working days are not greyed out on your Gantt Chart when working with Microsoft Project, right-click over the Timescale and from the shortcut menu, click Timescale. Select the Non-working time tab.

Select Behind task bars in the Draw section. From the Color dropdown, select an appropriate colour. If you are using a calendar other than the Standard calendar, select it from the Calendar dropdown. Click OK. Your non-working days will now be visible on your Gantt chart.

    HI, is it possible to grey out 2 hours every day as non-working times?
    Many thanks in advance.

      If you have changed the working time to reflect that there are 2 hours non-working time then if you zoom out to a large enough scale those two hours should be greyed out on the Gantt Chart

        Many thanks for the very fast reply.
        I guess I needed to be more clear. I already have an existing calendar for my project, and I want to adjust it to display the 2 hours every day (1 hour at start and end of shift – 2 x 12 hour shifts) that are non-working. Is there any easy way to do this?

    I can do it by adapting the 24 hour calendar to show 01:00 to 11:00 and 13:00 to 23:00, then adapt time for hours per day to 20 and hours per week to 100. Then over Gantt chart, right-click, then click Non-working time, and select 24 hour calendar. Would that work for you?

    Is there a way to change the appearance of a working day in the Gantt chart? There is a recurring day of special availability that I’d like to identify on the timeline by using a different color.
