CalCafe is a fast desktop calendar that keeps every event on your own computer - no account, no cloud, and fully usable with no connection at all.
Type "Team meeting Tue 3pm 1h #work every week" and it's on the calendar. Drag a to-do onto Thursday afternoon to book time for it. Glance at the icon by your clock to see what's next, start a focus countdown when a meeting begins, and check how many hours went to work versus everything else - all in one clean, quiet window.
Highlights
- Add events by typing a sentence - dates, times, lengths, repeats, reminders, places and categories in one line - "Lunch tomorrow 12pm @Cafe #personal". Works in English and Vietnamese, with or without accents.
- To-dos you drag onto the calendar - keep a list in the sidebar, give each item a length, and drop it on the week to book the time. The list shows what is booked and when.
- Where your time goes - hours per category for the week or month, day-by-day bars, your busiest day, and the change against last week.
- Next event by the clock - the icon near your clock shows "Standup in 12m" or how long the current meeting has left.
- Focus timer - a countdown for the length of an event, started from the event or automatically when it begins - pause it, stop it, and get a nudge when time is up.
- Event templates - save "1-on-1, 30 minutes, Work, 10-minute reminder" once and create it again in one click.
- Holidays & lunar dates - public holidays for Vietnam, the United States, the United Kingdom, China and South Korea, plus lunar day numbers on every date - including Tet, Mid-Autumn and the first and fifteenth of each lunar month. No connection needed.
- Month, week & day views - jump to Today, see a live "now" line, and switch with
M/W/D. - Quick event management - click any day or time slot to add; edit or delete in one panel. All-day and timed events supported.
- Recurring events - repeat daily, weekly, or monthly, with an optional end date.
- Reminders - a per-event reminder pops up a desktop notification, from "at time of event" up to a day before.
- Color-coded categories - General, Work, Personal, Health, Social, Travel - each toggleable as a sidebar filter.
- Search & mini-calendar - find events by title, location, or notes; navigate months with dotted day markers.
- Light & dark theme - follows the system, with a manual toggle.
- Bring your calendar with you - import events from Google Calendar, Outlook or Apple Calendar without losing what is already here, export a file any calendar app can open, or back up everything in one file.
- Always-visible widget - a compact month and agenda in a small window of its own; drag it wherever you like and click a day to jump the main window there.

How it works
Open the app and you land on the current month. Type an event into the box at the top of the sidebar, or click a day or a time slot to fill in the details yourself. Jot down to-dos as they come up and drag them onto the week when you know when they fit. Everything is written straight to your own machine, so it opens instantly, never waits on a network, and leaves nothing behind on anyone else's server.
Perfect for
- Privacy-minded people - who want a calendar that never leaves their machine.
- Focused planning - a distraction-free window for your week, separate from your browser.
- Keyboard-driven users - press Q, type a sentence, hit Enter; navigate the rest with single keys.
- Offline & travel - plan on a plane; no sync required.
