How to Track Your Cycle in Google Calendar

You already live in Google Calendar — your meetings, workouts, and plans are all there. So it makes sense to want your menstrual cycle there too, right alongside everything else. When you can see your phases next to your schedule, it’s far easier to plan a big presentation for your high-energy days and protect rest for your low-energy ones.

The problem is that Google Calendar wasn’t built for cycle tracking, so most people end up stitching together workarounds. Below we’ll cover the manual methods, where they fall short, and the simplest way to get your cycle — and your four phases — onto your calendar automatically.

Why Track Your Cycle in Google Calendar?

A dedicated period-tracker app lives in its own silo. Google Calendar is where you actually plan your life. Bringing the two together means you can:

• See which phase a given day falls in before you schedule something demanding.
• Plan workouts, deep work, and social events around your natural energy.
• Get period and phase reminders in the same place as the rest of your day.
• Share a calendar with a partner without handing over a separate app.

New to the idea? Start with what cycle syncing is.

The Manual Ways (and Where They Fall Short)

1. Add events by hand. You can create an all-day event on day 1 of your period and set it to repeat every ~28 days. It’s free and quick — but cycles aren’t perfectly 28 days, so the prediction drifts, and you only get “period,” not your four phases.

2. Google Sheets + Apps Script. There are scripts that read period dates from a spreadsheet and write events to a calendar. Powerful, but you’re maintaining code and updating a sheet every month.

3. Browser add-ons and extensions. Some period apps offer add-ons that push your logged period into Google Calendar. Helpful, but usually one-directional and limited to the period itself — not the follicular, ovulatory, and luteal phases that make cycle syncing actually useful.

The common gap: these get your period onto the calendar, but not your phases — and they rarely sync both ways.

The Easier Way: Sync Your Phases Automatically With Kilova

Kilova was built specifically to bring your cycle into the calendar you already use. Once you connect your Google account, it keeps everything in sync automatically — and it puts all four phases on your calendar, not just your period.

Here’s how to set it up:

1. Create your Kilova account and enter your last period date and average cycle length so it can map your phases.
2. Open the profile tab and choose Google Calendar Sync, then connect your Google account. The connection status will show “Connected and auto-syncing.”
3. Turn on “Show cycle phases on Google Calendar.” This overlays your menstrual, follicular, ovulatory, and luteal phases directly onto your Google Calendar.
4. Use Import and Export to keep events flowing both ways — pull your existing Google Calendar events into Kilova, and push your Kilova events and routines back out.

That’s it. From then on, your phases update on their own as your cycle shifts, so you’re never re-entering dates or fixing a drifting repeat event.

What You Can Do Once Your Cycle Is on Your Calendar

This is where it gets useful. With your phases visible, you can:

• Plan by energy — book intense workouts and big meetings in your follicular and ovulatory weeks, and lighter, detail-focused work in your luteal and menstrual days.
• Set phase-based routines — Kilova’s “Phase repeat” lets a task automatically recur through a whole phase, like iron-rich meals every day of your menstrual phase or strength training through your follicular phase.
• Stop guessing — instead of counting days, you glance at your calendar and know exactly where you are.

Frequently Asked Questions

Can Google Calendar track my period on its own? Not really. You can fake it with a repeating all-day event, but Google Calendar has no concept of cycle phases or variable cycle length, so it drifts and only ever shows “period.”

Does syncing go both ways? With Kilova, yes — you can import your existing Google Calendar events and export your Kilova events and phases, and the connection auto-syncs.

Will my cycle be visible to people I share my calendar with? Only if you share that calendar. You control sharing in Google Calendar exactly as you do for any other calendar.

Put Your Cycle Where You Already Plan

Tracking your period in a separate app and planning your life in Google Calendar keeps the two disconnected. Bringing your phases into your everyday calendar is what turns cycle awareness into something you actually act on. Try Kilova and see your whole month — phases and all — in one place.
