Pregnancy is a beautiful journey full of excitement, questions, and changes — especially if you’re becoming a mom for the first time. But one of the most common questions all expecting parents have is: “When will my baby arrive?” That’s where our Pregnancy Calculator helps. It gives you an estimated due date, tracks your week-by-week pregnancy progress, and helps you understand what’s happening inside your body.
Whether you're newly pregnant or just planning for it, this tool is your friendly guide. It’s quick, accurate, and totally free to use. You only need to enter the date of your last period (LMP), and the calculator does the rest!
A pregnancy calculator is a simple online tool that tells you your expected due date based on your Last Menstrual Period. But it does much more than that. It also shows you:
Many people think pregnancy is calculated from the day they conceived. But actually, doctors calculate it from the first day of your last menstrual period (LMP). That’s usually about two weeks before conception happens. This is a medical standard followed across the world.
So if your LMP was on January 1st, your estimated due date would be around October 8th — roughly 280 days (or 40 weeks) later. Our calculator uses the same logic to give you a reliable estimate.
Pregnancy is a 9-month journey filled with changes. Using a pregnancy calculator regularly helps you stay informed and ready. Here's why it's so helpful:
If you’ve missed your period and feel pregnancy symptoms like nausea or tiredness, take a home pregnancy test. These tests detect hCG (the pregnancy hormone) in your urine. They are quite accurate if taken a few days after your missed period.
If the result is positive, it’s important to visit a doctor for confirmation and start prenatal check-ups. Early care keeps both you and your baby healthy.
One of the best things about our calculator is that it breaks down your pregnancy into weeks. Each week brings something new — your baby’s size, features, or movements, and your body’s changes like mood swings, back pain, or cravings.
By checking the week-by-week progress, you can stay in sync with your baby’s development and know what to expect — like when the baby’s heartbeat starts or when fingers and toes form.
And most importantly — stay happy! A positive mindset and emotional support go a long way.
Pregnancy is a journey of 40 weeks — almost 280 days! So it’s smart to keep this calculator bookmarked. You can come back anytime to:
Whether you’re preparing for motherhood or already expecting, our Pregnancy Calculator is your simple companion. It brings you closer to your baby every day — with clear, useful, and loving guidance.
