Public transport services when switching to summer time

Finland will switch to daylight saving time or summer time on Sunday morning, i.e. clocks are turned forward an hour at 3am (3am > 4am).

Early morning bus services, i.e. Saturday service will run on winter time.  Beginning from Sunday morning service, transport services operate on summer time. There will be additional bus services on the night of Saturday to Sunday.
