Turn a list of events into calendar invites

Anything that runs to a schedule ends up needing this. A workshop with five sessions, a training programme, an onboarding plan with checkpoints at day one, day seven and day thirty. The plan exists, it is agreed, and it is sitting in a document where it will be read once and then quietly ignored, because a document does not interrupt anybody.

Getting it into calendars is what makes a plan real. An event in a calendar arrives with a reminder, shows up as busy, and survives the week that everything else falls out of. A plan that exists only as a list of dates is a plan that depends on somebody remembering to look at it, which is a poor thing to depend on.

The .ics format is the reason this is possible without asking everyone to use the same system. It is the one thing Outlook, Google Calendar and Apple Calendar genuinely agree on, so a file made here opens for a client who uses something you have never touched. That is worth more than a slicker integration with one platform.

Two details matter more than they look. The first is duration rather than end time: people think in forty five minutes, not in until 15:45, and the mismatch is where mistakes creep in when a list is typed at speed. The second is time zone, which is invisible when everyone is in one place and unforgiving the moment they are not. An invite carrying the wrong zone is worse than no invite, because everybody trusts it.

For a facilitated session there is a related discipline worth borrowing. Sending the calendar invites before the session rather than after it changes attendance, because the meeting is now in the way of people's other commitments rather than competing with them. It is a small mechanical thing that does more for a workshop series than most of the preparation.

This runs in your browser, which for scheduling is less about secrecy than it looks. A list of sessions still tells you who is working with whom, when, and about what, and a client's programme schedule is not something to hand to a free service in exchange for a file you could make yourself.
