Schedules for people
Rotas, weekly work schedules and class or study timetables.
Project plans
Tasks laid out against dates, with start, length and order.
Pick the planner by what repeats. A shift rotation generator suits a pattern that cycles, such as a few days on and a few off across a team. The work schedule maker is for a specific week of who works when. The timetable maker lays out lessons, classes or study blocks in a grid. The Gantt chart maker is for one-off projects, where tasks overlap and one starts after another ends.

Some planners can save a layout in your browser's local storage, and share links carry the plan's settings in the address, so only send a link to people you are happy to see the plan.
