Make an Invite Card and Matching Calendar File

A printed invitation gets pinned to a fridge. A calendar entry gets a reminder. Guests who get both are the ones who turn up on the right day at the right hour, and Invite and Calendar Maker is the shortest route to making both. It is a three-step workspace: guests, an invitation card and a calendar invite file, with the guest list and schedule shared between the steps.

This post is about the part that decides whether the pair actually matches: which of the two calendar files to send, how the schedule mode works, and how to check the finished card and file against each other.

The three steps

Step 1 opens Guest List Tracker. Its note in the workspace counts your guests. You only need it if you want personalised cards, but it also supplies the names for them.

Step 2 opens Invitation Card Maker. Pick one of six occasions (Birthday, Wedding, Baby Shower, Anniversary, Graduation or Corporate Event), type the headline, event title, message, date, time, venue and RSVP line, and add a background photo if you want one. The card can be printed, saved as a PDF (Letter), downloaded as an image, or exported as a print-shop PDF. With guests in the project it can also make one card per guest in a ZIP.

Step 3 opens Calendar Invite Maker. Its note says either how many sessions are in your agenda, or "Type the event details" if there are none.

The project lives in your browser tab, is not stored on our servers and disappears when you close the tab. Save the project file if you want to come back.

Two calendar files, and why they differ

The card step has its own button, Download Calendar Reminder. It takes the card's date and time and writes an .ics file with a two-hour event, the card's headline or title as the summary, the message and RSVP line in the description, the venue as the location, and a reminder one day before. It stores the time as a floating local time. That means the file says "18:00 on that date" with no time zone, and each guest's calendar shows 18:00 in whatever zone it is set to.

The step 3 tool is built for the case where the time zone matters. You choose the zone the event happens in, and it stores the exact moment in UTC, so guests elsewhere see the time converted to their own zone. It also lets you set the end time, a link, details, a reminder, and a repeat.

A simple rule: for an in-person event where everyone is in the same place, the card's own file is enough and always matches the card. For a webinar, a family event with relatives abroad, or a trip, use step 3 and set the zone.

A worked example: a two-day offsite

The sample project is a two-day company offsite in America/New_York with six sessions. Open the Calendar Invite Maker and choose "My project schedule", set a reminder of 15 minutes before, and download. The file contains 6 events, all named for the sample offsite:

• Welcome and goals, 13 November at 09:00 to 09:30, stored as 14:00 to 14:30 UTC.
• Roadmap workshop, 09:45 to 11:30, stored as 14:45 to 16:30 UTC.
• Customer panel, 13:00 to 14:00, stored as 18:00 to 19:00 UTC.
• Team dinner, 19:00, which has no end time, so it gets one hour, and is stored as 00:00 to 01:00 UTC on 14 November because 19:00 in New York is already the next day in UTC.
• Planning sprint, 14 November, 09:30 to 12:00, stored as 14:30 to 17:00 UTC.
• Wrap-up, 12:00 to 12:30, stored as 17:00 to 17:30 UTC.

Each session's room becomes the event's location, its link becomes the event's URL, and the presenter and track go into the details, after the event name. Guests see local times in their own calendars with no further work, and the calendar is named after the project. A session with a missing title, date or time, or an unknown time zone, is skipped, and the tool tells you which ones, rather than producing a broken file.

Details that save a correction email

For a single event the page asks for a title, the date, a start and end, the zone, where it is, a link and details. It will warn you if the time falls on a clock-change day, because that time either happens twice or not at all. For example 01:30 on 29 March 2026 in Europe/London does not exist, and the tool uses 02:30 BST and says so.

Repeating events are weekly or monthly, and you must choose the last day. For a repeat in a named zone, the tool adds the zone's clock changes to the file, so a weekly 19:00 meeting stays at 19:00 on the wall clock after the clocks change.

All-day events work differently for reminders. An all-day event starts at midnight, so a reminder "before" would ring in the night. The tool offers "9:00 on the day" and "9:00 the day before" instead.

"Add to my project schedule" adds the one event you just described to the schedule, but only timed events can go there, not all-day ones.

Check the pair before you send

Open the card and the calendar file side by side and read these four lines: the date, the start time, the place and the RSVP detail. If the card says "7 PM" and the file says 19:30, one of them is wrong. If the event is in another time zone from some guests, check what a guest would see by creating the file in your own zone and in theirs, and compare the stored UTC time in the example above. A guest opening the file in Google Calendar, Apple Calendar or Outlook gets the entry added at the right time.

Steps

1. Open the workspace and, if you want named cards, add guests in step 1.
2. Design the card and read the date, time, venue and RSVP line twice.
3. Decide which calendar file fits: the card's own file for a local event, or step 3 for any event where the zone matters.
4. In step 3, choose One event or My project schedule, set the zone and reminder, and download the .ics file.
5. Send the card and the file together, and say in the message which time zone the time is in.
6. Save the project file.

Invite and Calendar Maker and the Invitation Card Maker are Premium Applications with 2 trial uses a day before a day pass or plan applies. Calendar Invite Maker is a Professional Tool with 10 trial uses a day. Downloads count as usage.

Common mistakes

Typing the time on the card as "7 PM" while the file holds a different start time. Using a floating-time file for a remote event. Forgetting to set the last day of a repeating event. Choosing an all-day reminder of "15 minutes" and wondering why it never rings at a useful hour. Closing the tab before saving the project.

Summary

A card tells people; a calendar file reminds them. Make both from the same details, pick the calendar file that matches your time zone situation, and compare the four key lines before you send. Open Invite and Calendar Maker with your event details. For the single-tool walk-through of the calendar side, see make an ICS calendar invite for events. More planning tools are under event tools.
