Periodic Calendar

Periodic Calendar is a handy little software tool designed to help you keep track of your menstrual cycles and pinpoint those all-important fertility periods. It works on all versions of Windows, as long as you have the Java environment set up on your computer.

Easy-to-Use Layout

This program has a clean and simple layout that makes it super easy to navigate through the built-in calendar. You can quickly jump to the next or previous month, skip ahead or go back a year, and even find today's date in just a click! If you ever get stuck, there's a help manual available to guide you through any tricky parts.

Store Your Notes

With Periodic Calendar, you can save multiple notes for any day of the week. There are preset hotkeys that let you add records about menstruation, ovulation, pregnancy, childbirth, or even pregnancy termination with just a few keystrokes!

Easily Track Your Cycle

The calendar entries pop with different colors for easy spotting. For example, your first day of menstruation shows up in red while those fertile days are highlighted in green. This way, you won't miss important dates!

Statistics & Customization

You can also delete records and get useful stats about your cycles like minimum, average, and maximum lengths. Plus, there's a period length histogram to visualize it all. The program even supports the symptom-thermal method to help identify fertile windows.

Color Customization & Data Management

If you're someone who loves personalization, you'll be happy to know you can change the colors for various cycle events like the start of menstruation or fertility days. You can tweak prediction settings too and easily import/export your data!
