The first input is a date picker where you can select the first day of your most recent period. This is the foundation for the tool’s calculations. - Enter Your Average Cycle Length
Your cycle length refers to the number of days between the first day of your period and the day before your next period begins. Enter your average cycle length (between 21 and 35 days). The default is set to 28 days, but feel free to adjust it according to your cycle history. - Enter Period Duration
This field refers to how long your period typically lasts. The period duration can range from 2 to 10 days. Enter your typical period length to get accurate results. - Choose How Many Months Ahead to Calculate
This dropdown allows you to select how far into the future you want the calculator to predict. You can choose from:- 3 Months
- 6 Months
- 12 Months
- Click on “Calculate”
Once you’ve filled out the necessary details, click on the “Calculate” button to generate your upcoming period dates, ovulation date, and fertile window. - Reset the Tool
If you need to start fresh or change any details, click on the “Reset” button. This will clear all your inputs and give you a blank slate.
Example of Using the Period Calendar Calculator
Let’s walk through an example:
- First Day of Last Period: May 1st, 2023
- Cycle Length: 28 days
- Period Duration: 5 days
- Calculate Months Ahead: 6 months
Step-by-step results:
- Next Period: If your cycle is regular, the tool will predict that your next period will start on May 29th, 2023 (28 days from May 1st). It will continue to predict the start and end dates for every subsequent period for the next six months.

- Fertile Window: Your fertile window is typically the 5 days leading up to ovulation, and the day of ovulation itself. So, for this example, your fertile window would be from May 10th to May 15th, 2023.
