Quick answer: Maryland decides custody on the child’s best interest, may award joint custody, and says neither parent is presumed to have a superior right. For child support, shared physical custody means each parent keeps the child overnight for more than 25% of the year, which is 92 overnights, while both contribute to the child’s expenses.
This Maryland parenting time calculator turns a schedule into overnights a year and compares it with the 25 percent line in Md. Family Law 12-201. Enter the overnights in a 14-day cycle and any extra nights: the result is arithmetic, and the court decides custody and support.

What does this parenting time calculator check?
You enter the overnights the other parent has in a typical 14-day cycle and any extra overnights a year, such as summer and holidays. The calculator scales the cycle to 365 nights, adds the extras, and shows the overnights and percentage for each parent and whether both are above 25% of the year. It does not check the second part of the definition, that both parents contribute to the child’s expenses, and it does not calculate child support: use the Maryland child support calculator for that, and the Maryland divorce timeline calculator for the dates of the case.
