# plan9-cal(1)

print calendar

## NAME

cal - print calendar

## SYNOPSIS

**cal** \[ *month* \] \[ *year* \]

## DESCRIPTION

*Cal* prints a calendar. *Month* is either a number from 1 to 12, a lower case month name, or a lower case three-letter prefix of a month name. *Year* can be between 1 and 9999. If either *month* or *year* is omitted, the current month or year is used. If only one argument is given, and it is a number larger than 12, a calendar for all twelve months of the given year is produced; otherwise a calendar for just one month is printed. The calendar produced is that for England and her colonies.

Try

```
	cal sep 1752
```

## SOURCE

**/src/cmd/cal.c**

## BUGS

The year is always considered to start in January even though this is historically naive.

Beware that refers to the early Christian era, not the 20th century.
