Catholic Reminders + Gemini: put the week's feasts and holy days on Google Calendar

Catholic Reminders lists the week's feasts, holy days, and fast and abstinence days on the U.S. Roman calendar, with Mass reading citations that link to the USCCB. Google's help pages say Gemini can create events in Google Calendar once it is connected. Here is how the two fit together, what works today and what to check first.

Key takeaways

The short version.

  • Catholic Reminders lists feasts, holy days, and fast and abstinence days for the days ahead, using the U.S. Roman calendar. Reading citations link to the USCCB.
  • Google's help page says Gemini can create, find and edit events in Google Calendar once Google Workspace is connected and Keep Activity is on. Events go on your default calendar unless you name another.
  • Google's help page says a custom app can be added from an MCP server URL in the Gemini web app, under Settings and Connected Apps, in English. Gemini asks you to confirm write actions.
  • If you cannot add the connector, ask Catholic Reminders from its own site or another assistant and paste the list into Gemini. It is more manual, but it works.
  • Nothing here is a partnership, listing or built-in integration with Google. Catholic Reminders is independent and not endorsed by the Vatican, the USCCB or the Catholic Church. Local rules may vary, so check your diocese.

  • Gemini is Google's AI assistant.

It is for Catholics who already plan their life in Google Calendar: a parent fitting a holy day around school and work, a parish volunteer, a catechist, or anyone who wants Sunday and the days ahead visible next to everything else.

Catholic Reminders supplies the Church side. It follows the U.S. Roman calendar, lists feasts, holy days, and fast and abstinence days, and gives Mass reading citations with links to the USCCB. It is an independent resource, not endorsed by the Vatican, the USCCB or the Catholic Church.

Gemini is Google's AI assistant. Together they split the work: the app says what the calendar holds, and Gemini places it on the calendar you already use.

Use cases

4 ways people use Catholic Reminders + Gemini.

  1. Week on the calendar

    1. Add the week's feasts and holy days to your calendar

    Ask Catholic Reminders for the feasts, holy days, and fast and abstinence days over the next week. Then ask Gemini to add each one to Google Calendar as an all-day event, using the names and dates the app gave.

    Google's help page says Gemini creates events on your default calendar unless you specify another, and that you can select Undo in the confirmation notification. Check the dates against the list before you rely on them.

  2. Reading links

    2. Keep the readings one tap away

    Catholic Reminders gives citations and links to the USCCB, not the text of the readings. Ask Gemini to put the Sunday citation and its link in the event, so the reading is one tap from your calendar.

    Google's help page says Gemini cannot change the description of an existing event. Include the citation and link in your first request, or add them in Google Calendar yourself.

  3. Fasting days

    3. Plan around fast and abstinence days

    Ask for the week's fast and abstinence days and have Gemini mark them in a color or with a clear title. Your own meal planning and family schedule can then sit around them.

    The app reports what the Church asks on the U.S. calendar. It does not tell you how to meet your own circumstances. For that, speak with your pastor.

  4. Shared dates

    4. Share the dates with your household or parish

    Google's help page says Gemini cannot add or invite people to events. Create the events with Gemini, then share the calendar or invite people yourself in Google Calendar.

    A parish team can use the same list to draft a bulletin note in Gemini. Read it over and check it against your diocese before it goes out.

How to

How would I use Catholic Reminders with Gemini?

  1. Step 1

    Sign up free at [catholicreminders.org](https://catholicreminders.org), open the Connect your AI page and create a personal token. Save it, because it is secret. The MCP address is https://catholicreminders.org/api/mcp.

  2. Step 2

    On a computer, go to gemini.google.com, open Settings, then Connected Apps, and add a custom app with that address. The app uses a token, so if Gemini offers a place for credentials, enter your token there.

  3. Step 3

    Connect Google Workspace in Gemini and make sure Keep Activity is on. Then mention Google Calendar in your prompt, for example with @Google Calendar.

  4. Step 4

    Ask what this week means in the Church calendar, then ask Gemini to add the feasts and holy days. Confirm each action Gemini asks about and check the dates.

Google limits custom apps to the Gemini web app and English for now, and its help pages list further account and region requirements, so follow the current page. Catholic Reminders is not listed in Gemini's directory or built into Gemini. If you cannot connect, ask the app from its own site and paste the list into Gemini.

FAQ

Frequently asked questions.

Is Catholic Reminders a built-in Gemini integration?

No. There is no official partnership, listing or built-in integration. You may add its connector address as a custom app, the way you would add any compatible MCP server.

Does Gemini add events without asking?

Google's help page says Gemini currently asks for manual confirmation before write actions from a custom app. You can also select Undo in the notification after an event is created.

What if I cannot add custom apps?

Ask Catholic Reminders from its own site, then paste the list into Gemini and ask it to create the events. It is more manual, but it works without a connection.

Does it replace my diocese or my pastor?

No. Catholic Reminders is independent and not endorsed by the Vatican, the USCCB or the Catholic Church. It follows the U.S. Roman calendar, and local rules may vary, so check your diocese.
