The week tokens [ew] and [eww] work the same way as do the week number tokens [w] and [ww], except that they display the School Week Number as used in Estonia.
The Estonian school week numbering follows the same rules as that of the ISO week number, except that it is based on September 1, rather than January 1. That is to say, the week 1 of the Estonian school calendar is the week that contains the first Thursday of September.
