Beta Calendars Studio
Offline-first calendar layout and civil-date tools for Linux. Browse month and year grids, compare Monday-first and Sunday-first layouts, inspect ISO week boundaries, design printable blank calendars, and export SVG layouts without uploading personal calendar data.
Calendar views
Browse individual months or a full year with Gregorian calendar calculations. Switch between Monday-first and Sunday-first layouts, show week numbers or adjacent dates, and inspect each month’s natural four-, five-, or six-row grid.
Blank Calendar Designer
Create printable blank calendar layouts with A4 or US Letter paper, portrait or landscape orientation, Monday or Sunday week starts, notes margins, writing lines, week numbers, and optional fixed six-row layouts. Export layouts as SVG.
Date Inspector
Inspect a civil date, including its weekday, day of year, ISO week and week-based year, month length, quarter, leap-year status, days remaining, and Monday-first or Sunday-first grid geometry.
Calendar Lab
Review month geometry and run calendar checks for leap years, century rules, year boundaries, and weekday continuity.
Command line
Use the same calendar engine from the terminal:
betacalendars month 2027 2 --week-start monday
betacalendars year 2027 --week-start sunday
betacalendars inspect 2027-01-01
betacalendars grid 2027 8

Privacy
Core calendar calculations run locally. The app does not require an account or transmit personal calendar data.
Online calendar resources
Beta Calendars Studio works independently of the website. These optional links provide human-readable and printable calendar references; the app opens them only when you choose a link.
