Click + New Event or press N. Set the title, calendar, category, date, times, colour, and recurrence. Tick All day for full-day events. Tick Milestone / deadline to mark it as a diamond-shaped marker rather than a time block.
Tick All day, then fill in the End date field that appears to colour-code a whole span — e.g. one person's vacation — in a single entry instead of adding it day by day. It shows on every day of the range in Week, Day, Month and Agenda views.
Manage calendars in the left sidebar. Point at a calendar and click the tick on the right to hide or show it. Double-click a calendar name to edit its name or colour. + Add calendar adds a new calendar, links an Outlook or Google calendar, or subscribes to bank holidays.
Assign a category to an event — it appears as a small badge on event chips and in the detail panel. Add or remove your own categories (e.g. "Vacation") in Settings → Categories.
Press Ctrl+F or click the search box. Results match the title, description and category across a year either side of today. Click any result to jump to that day.
Everything is saved on your PC - events, calendars, notes, templates and categories. No account is needed, and Calendar works fully offline.
