Calendar - free
See your work the way you need it: a time grid for the day or week, a Gantt-style timeline, the month with ISO week numbers, or a two-week agenda. Drag to reschedule, drag an edge to change how long it runs, and undo with Ctrl+Z. UK bank holidays are already in. Free, with no account.

Click + New Event or press N - or click an empty slot in Week or Day view, and drag down to set the start and end in one go.
Day, Week, Timeline, Month and Agenda are along the top - or press 1 to 5. Week and Day shade your working hours; the Timeline opens at the start of your day.
Drag an event to another time or day. Drag its bottom edge to make it longer or shorter, in 15-minute steps. Ctrl+Z undoes it.
Make an event repeat daily, on weekdays, weekly or monthly, and give the series an end date when the job finishes.
Tick Milestone / deadline for a diamond marker, or All day with an end date to colour a span such as leave or a shutdown.
