Text calendar generator
Print a month or a full year as a plain-text calendar, aligned into columns.
Text calendar generator
Paste this into a plain-text note, a README, a terminal banner or a code comment: this tool prints a calendar for one month, several consecutive months, or a whole year, laid out entirely with monospaced characters so every column of dates lines up without a table or an image.
Set the starting month and year, or leave both blank to start from today. "Number of months" extends the range forward from that starting point, and "Months per row" places that many month blocks side by side instead of stacking them, which is how a full year becomes a compact 3×4 or 4×3 grid instead of twelve tall columns. Choose whether weeks start on Monday or Sunday, switch on ISO week numbers, or turn on "Workdays only" to drop the weekend columns entirely for a work-schedule view. A list of dates in "Highlight dates" — birthdays, holidays, deadlines — gets wrapped in brackets wherever it appears, and the "Names language" option prints month and weekday names in a language of your choosing, independent of the page you're reading this in.
The calendar itself always uses real calendar arithmetic: month lengths, leap years and ISO 8601 week numbers are computed directly rather than approximated, so February 2028 correctly shows 29 days and a Sunday-first layout groups the same days into weeks as a Monday-first one, just in a different column order. Choose "Spaced" for a minimal, whitespace-aligned grid or "Boxed" for one with ASCII borders around every cell.
Everything runs in your browser: nothing about the month, year or the dates you choose to highlight is ever sent anywhere. When the result looks right, copy it, download it as a .txt file, or send it straight into another tool's input.
