Maternity/Paternity Leave Calculator

Enter the expected delivery date and the tool calculates the standard Japanese leave periods: prenatal leave (from 6 weeks before the due date, or 14 weeks for multiple pregnancies), postnatal leave (8 weeks after birth), and childcare leave (until the child turns one). Use the dates as a planning guide for informing your employer, arranging handovers, and timing nursery-school applications. Actual entitlements can differ by employer and personal circumstances, so confirm details with your workplace or the relevant public office.
