50 days as needed. Another way money could come in was by initiating large building projects. As with tournaments this would first drain the coffers but with the influx of laborers, masons, and carpenters, as well as pilgrims if the building is a sizable cathedral, the lord would eventually make back much more in taxes than they spent. While the lord himself might not make it, the dynasty would benefit from the income. As to the knighting I don't know how it was handled in Austria but I believe anyone count or above could knight another. Maybe knights could do this as well. I haven't looked at medieval history in a while.
