A calendar invite is a digital request sent through tools like Google Calendar, Outlook, or Apple Calendar to schedule a meeting with one or more people. Writing a good one means including a clear title, the date and time, an agenda, and RSVP instructions — but before any of that, you need to actually create and send one. This guide covers both: the exact steps to send a calendar invite in the tools you already use, and how to write one that people actually read, prepare for, and show up to.
A calendar invite (also called a calendar invitation, meeting invite, or diary invite) is an electronic request sent through a calendar app that notifies recipients of a scheduled event and lets them accept, decline, or propose a new time. Unlike a plain email, a calendar invite automatically adds the event to the recipient's calendar once they accept, tracks who's attending, and can trigger reminders as the meeting approaches.
The exact steps vary slightly by platform, but the core process is the same everywhere: create an event, add guests, fill in the details, and send.
If you and the recipient don't share a calendar platform, or you're sending an invite through a plain email rather than a calendar app, most tools let you export an event as an .ics file. Open the event, look for an "Export," "Download," or share icon, and attach the resulting .ics file to a regular email. Most calendar apps will recognize the attachment and offer to add it automatically when the recipient opens it.
Once you know how to send one, the content of the invite is what determines whether people show up prepared — or at all. A professional calendar invite should include:
State the specific topic in the title itself — "Q3 Budget Review" tells people far more than "Meeting" or "Sync." A clear title helps attendees understand what they're agreeing to before they even open the invite.
One or two sentences in the description explaining why the meeting is happening and why the recipient's attendance matters. This is what turns a vague obligation into something people actually want to prepare for.
Always specify the exact date, start time, end time, and time zone — especially for remote or distributed teams. Include a video conferencing link or physical location near the top of the invite, not buried in the details. For recurring events, mark them clearly as such.
List 2–4 bullet points showing what you plan to cover. This lets attendees arrive prepared and gives them a sense of the meeting's flow before it starts.
Ask attendees to accept, decline, or propose a new time so you can finalize headcount and identify scheduling conflicts early, rather than discovering them the day of the meeting.
Include any documents, slides, or supplementary material attendees will need — attached directly to the invite rather than sent separately, so everything lives in one place.
Provide a way for attendees to reach the organizer or a point of contact if they have questions or need to make last-minute changes.
For meetings with a dress code, a specific format (e.g., cameras on), or other expectations that aren't obvious from the agenda alone, a short note in the invite prevents awkwardness on the day.
Automated reminders — whether built into your calendar tool or sent separately — meaningfully cut down on no-shows, especially for meetings booked more than a few days out.
Example calendar invite:

Beyond what goes in the invite itself, a few etiquette habits make a real difference in how your meetings are received:

A calendar invite is an electronic request sent through a calendar app — like Google Calendar, Outlook, or Apple Calendar — that notifies recipients of a scheduled event and lets them accept, decline, or propose a new time. It automatically adds the event to the recipient's calendar once accepted.
Both are correct and used interchangeably. "Calendar invite" is the more common shorthand in everyday workplace conversation, while "calendar invitation" is the slightly more formal, fuller phrasing. Neither is more correct than the other.
Export the event as an .ics file from your calendar app (usually found under an "Export," "Download," or share option) and attach that file to a regular email. Most calendar apps recognize .ics attachments automatically and prompt the recipient to add the event to their own calendar when they open it.
A "diary invite" is a common term, especially in UK and European workplaces, for what's more widely known as a calendar invite — a scheduled request sent to book time in someone's calendar (or "diary").
A professional calendar invite should include a clear title, a brief purpose statement, exact date/time/time zone, location or video link, a short agenda, RSVP instructions, any necessary attachments, and contact information for the organizer.
Keep the subject line specific rather than generic, state the meeting's purpose in one or two sentences, list a brief agenda so attendees can prepare, and include clear RSVP instructions. Avoid vague titles like "Meeting" or "Sync" — specificity is what gets people to actually prepare.
