There are two kinds of entry on a client's calendar and they behave almost identically.
- Programme entries were placed by assigning a programme. Moving or removing one only affects that client's copy of the programme.
- One-off entries were added directly to a date, assigned to the Train page, or logged by the client on their own.
Both can be moved, swapped, removed and completed in the same way, and both show in the activity feed. The only practical difference is where they came from.
