When an activity has "None" in the field/cell for calendar it just means that no calendar has been assigned to the activity and as default value takes the project calendar. "None" is therefore not a calendar, neither does it mean "Standard", but merely a reference to the calendar chosen to be the project calendar by the "planner".
Microsoft should maybe more logically have selected another word than "None", likewise they should have let the default calendar for resources to be the "none" instead of the "Standard" calendar, so calendars for the task and the resource where the same in those instances where people hadn't given the calendars any thoughts (and there are many of those people out there...)
I've just tried to make an actual calendar named "None" only allowing it to work Mondays (1 day pr. week) and assigning it to a task. However MSP couldn't handle that - it still used the default project calendar (working 5 days a week). Therefore, lesson learned: Never name a user-made calendar "None" in MSP.
When the activity Calendar is defined as "None", MSP is using the calendar you have defined as "Calendar" under "Project Information". For many users this will be the "Standard"-calendar (e.g. for those who just open a new file and start to plan without giving calendars any attention), however not for those users who have chosen another calendar to the be project calendar. That chosen project calendar will then be the "None"-calendar.
Be aware that for some strange reason resources are always using the "Standard"-calendar as their base calendar if nothing else applied, not the project calendar, meaning one can get into a bit of problems when the project calendar is another than the "Standard".
Therefore, always be in total control of all your calendars before starting to plan and do not assume that MSP will do the most logical.

Hi Bo
Thanks for the information - another good reason to avoid MSP.
You are quite correct that planners do not understand the significance of different calendars - particularly in respect of resources.
In PowerProject there is a tick box in the resource dialogue which says "Use Task Calendar" which keeps it very simple.
I once put together a complete EoT delay analysis and Acceleration claim using nothing but different calendars on the baseline.

Hi Bo
Surely a "None" calendar means a 24/7 construction period with no work pattern or holidays.
At least that is what it is in all other software I have used.
I don't use MSP so I would not be surprised to learn that None means Standard in their strange environment.
