Calendars in Phoenix keep track of holidays, weekends, and other periods of time in your project when work can't be done and must be delayed. The Calendar Creator can be found from the Info menu.

Only one calendar can be in use for your entire schedule as Phoenix does not support multi-calendar projects currently. If you selected the wrong calendar when first creating your project, you can either switch to one of the other default calendars by selecting it and clicking Set as Calendar, create a new one with the appropriate settings (see below), or modify the current calendar's settings.

The three default calendars included in all new projects are the 5 Day, 6 Day, and 7 Day calendars. The 5 Day calendar defines Saturdays and Sundays as non-work days by default, the 6 Day calendar defines Sundays as non-work days by default, and the 7 Day calendar doesn't define any non-work days.

Creating a New Calendar

You can create a new calendar by clicking Add New under Available Calendars, giving your new calendar a name, and selecting one of the following options:

• Duplicate Existing Calendar: This option will create a new calendar with the same non-work days as the selected calendar.
• Blank Calendar: This option will create a new calendar without any non-work days.

Setting up Non-Work Days

Non-work days can be added to any of the calendars including the default calendars by selecting the calendar you want to add them to, and adding one of the three types of non-work days that describes the behaviour you want for that non-work day.

• Single Non-Work Day: This is the most simple of the non-work types you can add to a calendar. Just select the day you want to make into a non-work day, and click the Non-Work button under the calendar. This will make that single day (of the selected month and year) into a non-work day and all activities that overlap that day will be pushed to finish one day later.
• Repeated Day of Week: This type of non-work day is used when you need a specific day of the week off every week or every few weeks.
• Repeated Day of Month: This type is used when a specific day of every month or year is needed. This type is most often used for setting up annual holidays (by setting that day to repeat every 12 months).

Any repeating non-work types start their repetition on the calendar day selected before pressing Repeat. Repeating non-work days can also be set to expire by a certain date. This can be used to when you need a repeating non-work for a certain period of time after which work continues normally.
