 Hi my name is Richard Walters. In this demonstration we look at calendars and the two big types of calendars resource calendars as well as project calendars. In this demonstration we're going to look at project calendars as well as resource calendars so both can be found in the project tab and then change working time. Now in this example when the first effect the project standard calendar and we're adding the Christmas break now this particular project example is starting in December 2023 so it will be affected by the Christmas break so we'll add the dates so we're on a standard calendar in the exceptions area and we're adding Christmas break put the dates in so we'll say 20 seconds until the second and if you click in a line below you'll then see the shading of what you've just done so you know that the dates have been affected and there we go. What will happen now in this case the project duration won't change that'll stay at 56 days but the finished date will that will move from under the 19th let's click okay to that and that's now gone to the 29th of February and the blue shows you all the attacks that are affected by that change. Now we're looking now in this example we'll look at the resource calendar non-working so same idea change working time and this time I'm going to put the HR manager on a training course for the HR induction we're going to go to the same idea but this time use a different calendar so HR manager exceptions we'll say some mandatory health and safety course and we'll say it's affecting HR induction so it's somewhere between the 16th of February and the 29th of February so we'll pick three dates between that so I'll go for the 20th to the 22nd and click below to see the change and there's the change the highlight of dates what'll happen in this case the duration will change by three days and the finished date will change by three days okay to that and there we go the finished date is now going into March we've gone on to 59 days I've got one more example of calendars in this case it's resource working time so I've got a different file to demonstrate so same kind of look to the file we're going to put the HR manager on here on part-time working because let's say the the person has just returned from maternity leave and we want to ease the person back into work so it's going to be part-time working and the person's already been allocated to the project full-time at this point in time so same idea change working time HR manager again and this time workweek's going to change the details for the workweek and when I say Monday to Friday I'm holding my shift key down and clicking on Friday I'm going to set these to specific work times and I'm going to take out the afternoon session so now I click on the gray box next to the afternoon session and delete it so we're going to now see that half the day has been taken away to a resource that's already been allocated what you'll see shortly is the afternoon session will disappear from the calendar and when I click okay the duration will change by a lot of days as well as the finished date will also change so we'll now click okay and there's the afternoon session gone click okay again and now we can see the impact that that has changed to over 100 days and the finished date has gone quite substantially but this now completes the training demonstration video on project calendars as well as resource calendars this now completes the demonstration of calendars and resource calendars see you in the next video
