How the Maternity Leave Calculator Works
This calculator helps you map out the timeline of your maternity leave around your baby's due date. You choose how many weeks of leave you want to take before the due date and the total number of weeks of leave. From that, it works out the date your leave begins and the date you are scheduled to return to work, so you can plan with your employer and organise cover for your role.
Leave Start = Due Date − (Weeks Before × 7 days)
Return Date = Leave Start + (Total Weeks × 7 days)
Frequently Asked Questions
When should my maternity leave start?
That depends on your health, your job, and the rules where you live. Some parents start a few weeks before the due date to rest, while others work right up to the birth. Set the "weeks before" value to 0 if you plan to start your leave on the due date itself.
What if my baby arrives early or late?
The dates here are based on your estimated due date. If your baby arrives early or late, or your leave is triggered by the birth, your actual leave dates may shift. Recalculate with the real birth date once it is known.
How long is maternity leave?
Statutory and paid leave length varies widely by country and employer, from a few weeks to over a year. Enter the total number of weeks that apply to your situation to see your return date.
Note: Maternity leave rules, entitlements, and pay vary by country and employer. This calculator provides a simple timeline estimate based on the dates you enter and does not constitute legal, financial, or HR advice. Always confirm your specific entitlements with your employer, your HR department, and the relevant laws where you live.
