The new format is a little cramped but it makes a\nyear fit on a 25x80 terminal. If arguments are not specified, the current month is displayed.\n\n## TLDR\n\n> Display a calendar with the current day highlighted.\n\n- Display a calendar for the current month:\n `cal`\n- Display a calendar for a specific year:\n `cal {{year}}`\n- Display a calendar for a specific month and year:\n `cal {{month}} {{year}}`\n\n*Source: tldr-pages*\n\n## Sections\n\n- **NAME**\n- **SYNOPSIS**\n- **DESCRIPTION** (21 subsections)\n- **SEE ALSO**\n- **STANDARDS**\n- **HISTORY**\n- **AUTHORS**\n- **BUGS**\n\nUse structuredContent.sections for detailed options, examples, and full documentation.\n" } ], "structuredContent": { "command": "cal", "section": "", "mode": "man", "summary": "cal, ncal — displays a calendar and the date of Easter", "synopsis": "cal [-3hjy] [-A number] [-B number] [[month] year]\ncal [-3hj] [-A number] [-B number] -m month [year]\nncal [-3bhjJpwySM] [-A number] [-B number] [-W number] [-s countrycode] [[month] year]\nncal [-Jeo] [-A number] [-B number] [year]\nncal [-CN] [-H yyyy-mm-dd] [-d yyyy-mm]", "tldr_summary": "Display a calendar with the current day highlighted.", "tldr_examples": [ { "description": "Display a calendar for the current month", "command": "cal" }, { "description": "Display a calendar for a specific year", "command": "cal {{year}}" }, { "description": "Display a calendar for a specific month and year", "command": "cal {{month}} {{year}}" } ], "tldr_source": "official", "flags": [ { "flag": "-h", "long": null, "arg": null, "description": "" }, { "flag": "-o", "long": null, "arg": null, "description": "Easter according to the Julian Calendar." }, { "flag": "-e", "long": null, "arg": null, "description": "" }, { "flag": "-j", "long": null, "arg": null, "description": "" }, { "flag": "-m", "long": null, "arg": null, "description": "Display the specified month.
