Months to Weeks Converter: Convert Months into Weeks & Days Instantly
Whether you're tracking a pregnancy due date (9 months), planning a 6‑month project, or converting a lease term — our Months to Weeks Converter gives you the exact number of weeks and remaining days, using standard or custom month lengths.
How to Use the Months to Weeks Converter
- Enter the number of months (e.g., 3, 6, 9). You can use decimals like 2.5 months.
- Choose month length – Standard (30.44 days) works for general conversion; use 30, 31, 28, or 29 for specific calendar months.
- Click Convert – the total weeks and remaining days appear instantly.
- Use preset buttons for common durations: pregnancy (9 months), quarterly (3 months), annual (12 months).
The converter uses the formula: total days = months × days per month, then weeks = floor(total days / 7), remaining days = total days % 7.

Example: 9 months in weeks (pregnancy)
Pregnancy is often described as 9 months, but medically it's 40 weeks from the last menstrual period. Using the standard average (30.44 days/month): 9 × 30.44 = 273.96 days → 39.14 weeks. Our converter shows both weeks and remaining days, helping expectant parents plan.
Why use average month length vs exact months?
Calendar months vary between 28 and 31 days. For general planning (e.g., “6 months from now”), the average (30.44 days/month) is most accurate. For specific legal or financial months (e.g., “June” with 30 days), select the exact length.
