The Dutch word [wanneer](javascript:void(0)) translates to "when" in English. The word [uitgerekend](javascript:void(0)) can mean "calculated" or "due" depending on context, but it is often used in pregnancy-related contexts to mean "due date" or "expected date of delivery" (literally "calculated date").
So, [wanneer uitgerekend](javascript:void(0)) would mean "when is (someone) due" or "when calculated," typically used to ask for the due date in terms of a pregnancy or other expected event. This phrase is commonly used in Dutch to inquire about the expected date of childbirth, referring to the estimated time when a baby is expected to be born based on a pregnancy calculation starting from the last menstrual period and typically lasting around 40 weeks.
