Bus transport for North Crete cities

Hello. I am planning my vacation in Crete from 19 June to 27 June. I want to stay in Rethymno and visit other north cities from there. I searched for transportation information and saw that there are buses of KTEL, I downloaded the timetable from this page: https://www.we-love-crete.com/ktel.html but it starts on 01 July. Aren't there buses for June?
Where can I find June timetable and prices?
Thank you in advance
