Modifying the number of hours or days make up days, weeks and months.

[G&G]

How can I adjust number of hours per day, days in month, and hours per week?

[Intaver Support]

In the Project Options > Calendar tab you can define the number of hours/day, hours/week, and days/month.
To set as default values for all new projects, click the Set as default button.

If I use schedule from Microsoft Project, does RiskyProject import this settings from the schedule, created in Microsoft Project?

Yes. It does.
