- .. method:: formatyear(theyear, themonth, w=2, l=1, c=6, m=3)
+ .. method:: formatyear(theyear, w=2, l=1, c=6, m=3)
Return a *m*-column calendar for an entire year as a multi-line string.
Optional parameters *w*, *l*, and *c* are for date column width, lines per
used.
- .. method:: formatyear(theyear, themonth, width=3)
+ .. method:: formatyear(theyear, width=3)
Return a year's calendar as an HTML table. *width* (defaulting to 3)
specifies the number of months per row.
