Personally I would like this.
And as Wouter wrote, adding some parameters would be nice. I would add: print_which (previous, current, next), print_interval (week, period, month, quarter, year), print_month (January, February, March, April, May, June, July, August, September, October, November, December), print_year (YY, YYYY), print_number (first, last, 1....9999), language_print (nl, du, fr, it, en, es).
