Rescheduling by Dragging
Month and Week views
Move an event by picking it up and putting it down
Drag an event to a different day in Month view, or to a different time slot in Week view. PrimeCal keeps the event's length, warns you if the new slot is already taken, and gives you one click to undo.
How to move an event
- Press and hold on an event. With a mouse that means pressing and starting to move; with a finger, rest it on the event for a moment (see below).
- Drag it to the day (Month view) or the time slot (Week view) you want.
- Release.
The event stays where you dropped it and a confirmation appears in the corner. If PrimeCal cannot save the move - the calendar is read-only, or the connection is gone - the event goes back to where it was and a message says so.
A drag only starts once you have moved the mouse about 5 pixels, or rested a finger on the event for about a third of a second. A plain click or tap opens the event for editing exactly as before, so you will not open the editor by accident when you meant to drag, or move an event when you meant to open it.
What is preserved
| You drag | What happens |
|---|---|
| A one-hour meeting to another day | Stays one hour, keeps its time of day |
| A 09:30–10:30 meeting down by about an hour in Week view | Moves by the distance you dragged, to the nearest quarter-hour, and keeps its minutes (10:30–11:30, not 10:00) |
| A three-day all-day event | Stays three days, starting on the day you dropped it |
| An event onto a different calendar's day cell | Moves day only; use the event editor to change calendar |
Dropping an event on a day in Month view keeps its time of day. In Week view the event moves by how far you drag it, in quarter-hours, so a 09:30 event nudged down a little lands at 09:45 rather than jumping to 10:00. This is deliberate: moving a 09:00 stand-up to next Tuesday should keep it at 09:00, not reset it to midnight.
Conflict warnings
While you drag in Week view, a dashed outline shows exactly where the event will land and what time that is. In Month view the day under the pointer is highlighted. Either way:
- Green — the slot is free.
- Amber — something else is already booked there.
Amber is a warning, not a block. Double-booking is sometimes exactly what you want, so the move still goes through and the confirmation tells you the new time overlaps another event. Open either event afterwards if you need to sort it out.
Two events that simply touch — one ending at 10:00, the next starting at 10:00 — are not treated as a conflict.
Changing how long an event lasts
In Week view, drag the bottom edge of an event up or down to shorten or lengthen it, again in quarter-hours. The confirmation has an Undo button too. From the keyboard, see below.
Events that repeat, span several days, or are reservations do not have the handle: changing one occurrence or the whole series is a decision for the event editor, which asks you.
Undoing a move
The confirmation that appears after a move includes an Undo button. Click it and the event returns to exactly where it was.
Undo stays available until the confirmation disappears (a few seconds). After that, drag the event back or edit it directly.
On a phone or tablet
With a finger, rest it on the event for about a third of a second. The event is picked up - on a device that can, with a short buzz - and follows your finger down the day or across to another day; lift to drop it. The dashed outline, the colours, the quarter-hours and the Undo work exactly as they do with a mouse.
- A swipe that starts on an event still scrolls. Move your finger straight away and the grid scrolls (or, sideways, pages the calendar) as it always did. Only resting first picks the event up, so you never move something just by scrolling past it.
- Dropping an event on another day does not page the calendar. A sideways drag of an event is not a swipe.
- The grid scrolls by itself when you carry an event to its top or bottom edge, so any hour can be reached without letting go. The page behind it stays where it is.
- Changing how long an event lasts: pull its bottom edge. On a touch screen that edge is a taller strip, up to about 6 mm - never more than the lower 40% of a short event, so a short one can still be picked up or tapped.
- Pulling the page down to refresh only happens from the very top of the screen. Scrolling the day back up, or carrying an event down, no longer refreshes the page.
On a phone the Month view shows each day as dots: tap a day to see its events, and tap one to open it. A tablet's Month view has room for the event bars, and those are picked up the same way.
Moving without a mouse
Every view that lets you drag lets you do the same from the keyboard:
- Tab to the event. (Enter opens it, as always.)
- Press Space to pick it up.
- Move it with the arrow keys:
- ← → one day;
- ↑ ↓ a quarter-hour in the Day, 3-day, Work week and Week views, or a week in the Month view.
- Press Space or Enter to drop it, or Esc to put it back.
While it is picked up, the dashed outline shows where it will land - green when the slot is free, amber when it overlaps something - and the arrows belong to the event: the calendar does not page, and the selected day does not move. In the time grids the event stays inside its day however long you hold an arrow. A screen reader says which event it is, its day and time after every step, whether it overlaps another event, and where it was dropped. When the event has been moved, the keyboard is on it again, and the same Undo is on screen.
Changing how long an event lasts, from the keyboard
In the Day, 3-day, Work week and Week views, hold Shift and press ↓ to lengthen the focused event by a quarter-hour, or ↑ to shorten it (never below a quarter-hour, never past midnight). Press as often as you like: the new length is saved once, a moment after the last press, with the same Undo as dragging the bottom edge, and a screen reader hears the new end after each press. Esc drops a change that has not been saved yet.
? lists these keys too, under On an event. See Search and Keyboard Shortcuts for the rest of the calendar shortcuts.
When dragging is unavailable
Events cannot be dragged when:
- you are offline — the calendar is read-only until the connection returns;
- the calendar was shared with you as read-only — you can see events but not change them;
- you are in Kid Mode, which is view-only by design.
In these cases events simply do not pick up, and clicking still opens them.
