Turn a Google Sheet into a live calendar

Your schedule already lives in a Google Sheet. CalRelay turns it into a calendar feed that anyone can subscribe to on Apple Calendar, Google Calendar, or Outlook. When you edit the sheet, subscribers' calendars update on their own.

There are no add-ons to install and no Apps Script to maintain. You don't export a new .ics file every time something changes. The sheet stays the source of truth.

Free plan, no credit card. No account needed to see your events.

Share your sheet as a link

In Google Sheets, click Share and set “Anyone with the link can view.” CalRelay only reads your sheet. It never gets edit access and never asks for your Google login.

Paste the link and map your columns

Paste the share link below. CalRelay reads your headers and suggests which columns are the title, date, time, and location. Then it shows you every event it found, along with any rows it couldn't parse, with the raw values so you can see what went wrong.

Send one link to everyone

You get a hosted subscribe page with one-click buttons for Apple, Google, and Outlook. Subscribers tap once and their calendar stays in sync after that. They never need an account.

Why not just export an .ics file from Sheets?

An export is a snapshot. Once the schedule changes, every copy people imported is out of date, and you have no way to push a fix to them.

A calendar feed is a subscription. CalRelay keeps polling your sheet, regenerates the feed when something changes, and calendar apps pick up the update on their own. Edits update the existing event in subscribers' calendars instead of creating duplicates.

What your sheet needs to look like

One row per event, with a header row. At minimum you need a title column and a date column. Time, end time, location, and description columns are optional. Everyday date formats work (3/4/26, Mar 4, 2026-03-04 7pm, March 4th @ 7), and you pick your locale so day-first and month-first dates are never guessed.

Rows CalRelay can't confidently parse are held and shown to you with the raw cell values. They're never guessed at and never silently dropped, so a TBD date doesn't become a wrong event on everyone's calendar.

What happens when someone breaks the sheet

If a column gets renamed or the sheet becomes unreachable, CalRelay freezes the feed at its last good state and emails you. Subscribers keep the last valid calendar instead of seeing an empty one. The feed-health panel shows what changed, and fixing the mapping takes a click.

Questions

Does my Google Sheet have to be public?

It needs link sharing turned on (“anyone with the link can view”) so the feed can read it. The sheet isn't listed anywhere, and CalRelay never gets edit access or asks for your Google login. If you turn sharing off, the feed pauses at its last good state and subscribers keep the last valid calendar.

How fast do subscribers see my edits?

CalRelay re-reads your sheet on a schedule: hourly on the free plan, every 15 minutes on Pro. Apple Calendar and Outlook subscribers usually see changes within about 15 minutes after that. Google Calendar fetches external feeds on its own schedule and can take up to 24 hours. That's a Google limitation that applies to every feed provider, and your subscribe page mentions it so subscribers know what to expect.

Do subscribers need a Google account or a CalRelay account?

Neither. They tap one button on your subscribe page and their calendar app handles the rest. It works with Apple Calendar, Google Calendar, Outlook, and anything else that can subscribe to a calendar feed.

What about recurring events?

Give each occurrence its own row: one for the practice on the 5th, another for the 12th. Exceptions are easy that way. Skip a week by deleting its row, or move one practice without touching the others.

Is there a free plan?

Yes. One feed with up to 50 events, refreshed hourly, free forever, no credit card. Pro adds more feeds, unlimited events, 15-minute refresh, and email alerts when a feed needs attention.

Your schedule already exists.
