NB. I use different colors for different locations, and be advised that travelling between the Kumpula and Otaniemi campuses takes 30-60 minutes depending on traffic. Scheduling a meeting for 8 am is possible, but given a choice, I prefer starting times after 9. Towards the evening I have more flexibility as I normally work quite late.
