Now that you have set the default working times for the project and defined days, weeks, and months, you can change the working times for selected dates and for days of the week in the Change Working Time dialog box. You can change selected dates from the default working time to nonworking,time or to non default working time. If, for example, your organization does not work on Martin Luther King Day, you could.
mark that day as nonworking time. Or, if your organization is open on saturday mornings, you could select Saturdays and include hours for that day.
To change the working times for any of the dates, you must first select the dates you want to change (see Table 6.1).
Editing the Calendar
To change a date to a nonworking date, select the date and click the Nonworking time option.
Project shades the date in the Calendar and underlines it to indicate that it deviates from the default calendar. January 17 is marked as a nonworking time in Figure 6.6.
You can also change the work schedule for a particular day of the week. To change the working hours of a day of the week, select the day by clicking the day header to select the entire column, and click the Non default Working Time option. Enter the scheduled working
time in the From and To fields, as shown in Figure 6.7. If times are already entered in the From and To boxes, you can delete them by dragging over them to select them and pressing Delete or entering a new time. Pressing Tab to move between the From and To fields automatically selects the contents.
When you have entered new times, Project designates the edited working hours with a lightly shaded pattern
Restoring the Default Working Times
If you want to change any of the calendar dates back to the default working times, select the dates and choose the Use Default option on the Change Working Time dialog box. ‘ote, however, that you may have changed the default for a particular day (for example, making Saturday a working day), and the Use Default option changes the particular date back to the new default for that weekday, not to the original default for that day. To change an entire weekday back to the original default, select the day column and choose Use Default.
Changing Other Calendars
After you make all the desired changes to the Standard calendar, you can edit the Night shift or 24 Hour calendars in the same way by choosing them from the drop-down list at the top of the Change Working Time dialog box. If the calendar you need is drastically
different from the Standard calendar or if you need to apply a special calendar to specific resources, you can create additional calendars.
Mastering Time Formats
Project accepts time entered using the 12-hour or the 24-hour clock. Ifyou use the 24- hour format, enter the time as 8:00, 13:00, 16:00, and so on. If you use the 12-hour format, you should enter a.m. or p.m. after the time to ensure that Project interprets the time correctly. Project assumes that the time you enter is after the Default Starting Time on the Calendar tab of the Options dialog box, and chooses the first occurrence of that time after the Starting Time. So, ifyou enter 10:00, for example, it assumes 10:00 a.m. Ifyou meant p.m., you must designate it as such.
It’s not necessary to enter the minutes if the time is on the hour. Project interprets 5 pm, 5 p.m 5:00 pm, and 5:00 p.m. in the same way.
Creating Additional Calendars
As you plan the project, you may already know that a resource you plan to use does not work in the schedule laid out in the standard calendar. With Project, you can create additional calendars, and you can apply the appropriate calendar to them when you assign these resources to the project (see ). If you don’t yet know the work schedules of all of the resources involved with the project, you can create the additional calendars as you discover then:t. To create an additional calendar, follow these steps:
1. Click the Tools menu, choose Change Working Time, and then click the New button in the Change Working Time dialog box.
2. Enter a name for the Calendar in the Create New Base Calendar dialog box, shown in Figure 6.8.
3. Choose Create a New Base Calendar it you want to starfwith a blank calendar that uses the default working times set on the Calendar tab of the Options dialog box. OR Choose the Make a Copy of Calendar optiori if you want to use an existing calendar
as the basis for the new calendar. From the drop-down list, select the calendar you want to base the new one on.
4. Click OK to start working on the new calendar If you made changes to the calendar you were working on, Project prompts you to save those changes before moving on to the new calendar. Click Yes to save the changes to the previous calendar or No to discard them.
5. Edit the calendar, as described in “Changing Working Times,” earlier in this
After you edit the new calendar, Project saves it automatically’ when you click OK to. close the Change Working Time dialog box, or it prompts you to save it if you create another new calendar
