The dates are locked, so someone sends a calendar invite: "Lisbon, Thu to Sun." A week later the group moves the boat trip from Saturday to Friday and books a dinner for Thursday night. The invite still says Thu to Sun with nothing in it, and the plan lives in a chat thread nobody can find on Friday morning.
In brief: put the trip on calendars once the dates are locked, not before. Keep the plan in one place and have that place update everyone's calendar, rather than sending corrections. A subscribed calendar does this on its own; a snapshot invite needs one owner who edits it.
Send the Dates When They're Locked
A calendar invite reads as a decision. Send one while the group is still choosing between two weekends and some people will book flights for the first one.
Wait until the dates are actually set, then send them the same day. That's when people block time off work and start looking at flights, so it's when the calendar entry is most useful.
Snapshot Versus Subscription
There are two ways to get a trip onto someone's calendar, and they behave differently once the plan changes.
- A snapshot. A calendar invite you send, or a calendar file someone downloads and opens. It copies the plan as it was at that moment. When the plan changes, the copy doesn't.
- A subscription. A link that the calendar app checks every so often. The app pulls the current plan each time, so changes show up without anyone resending anything.
A snapshot is fine for the dates alone, because locked dates rarely move. It goes stale fast for the plan inside those dates: which day the hike is, what time dinner is booked.
One Place for the Plan
Whatever you use, the plan should live in one place, and calendars should copy from it. When the boat trip moves, someone changes it there. Nobody posts "update: boat is Friday now" and hopes everyone edits their own calendar.
If you're using invites, that means one person owns the invite and edits the event itself. Most calendar apps send the change to everyone on the invite. A correction in the chat doesn't change anyone's calendar.
Check the Times Once
Calendar apps show times in the phone's own time zone. If the whole group lives in one city and the trip is in another time zone, a 7:30pm dinner can show up at the wrong hour.
Before you leave, have one person in the group open a timed item on their phone and check it reads right. Writing times in the destination's local time, and saying so in the plan, avoids most of the confusion.
Doing This in TRIPTI.ai
In TRIPTI.ai, anyone on a trip can subscribe their calendar to it from the trip menu, under Live calendar. Subscribe once and the trip's days stay current: each item on the itinerary appears as its own event, and if there's no itinerary yet, the locked dates show as one all-day event.
The calendar reads from the trip, so the plan is changed in the trip and the calendar follows. How quickly a change appears depends on your calendar app, since each one checks for updates on its own schedule, and some only a few times a day.
The subscription is a private link. Anyone who has it can see the trip's plan, so keep it in your own calendar rather than posting it in the group chat. If you leave the trip, the link stops working.
There's also a one-time "Add to Calendar" on the itinerary, which saves a snapshot. Use it when you just want the dates and don't need updates.
The live calendar is included in every trip.
Without the app, a shared calendar that one person maintains does the same job, as long as that person makes every change in the calendar itself and the group knows not to edit their own copies.
