Period Calculator

Introduction

A Period Calculator is a simple and effective tool designed to help women track their menstrual cycles. By entering the first day of your last period and your average cycle length, the calculator can predict your next period dates. This makes it easier to stay prepared, manage health, and track fertility. Whether you are planning a pregnancy, monitoring your reproductive health, or just want to avoid surprises, a period calculator provides quick and reliable results.

Formula / How It Works

The menstrual cycle usually lasts between 21 and 35 days, with the average being 28 days. The calculator uses the following formula:

• Next Period Date = First Day of Last Period + Average Cycle Length

For example, if your last period began on June 1 and your cycle length is 28 days, your next period is expected on June 29. If your cycle length is 30 days, then your next period should arrive on July 1. This straightforward calculation helps you anticipate upcoming cycles with ease.

Step-by-Step Usage

1. Enter the first day of your last period.
2. Select your average cycle length (e.g., 28 days).
3. Click on Calculate to get the date of your next expected period.
4. The tool will also predict your future cycles for better planning.
5. Use this data for tracking fertility, travel planning, or medical consultations.

Examples

• Example 1: Last period: May 5, cycle length: 28 days → Next period: June 2.
• Example 2: Last period: July 10, cycle length: 30 days → Next period: August 9.

These examples show how the calculator gives accurate predictions based on your personal cycle length.
