 How interesting. We can see that the group is most active between the end of January till May and spikes again in October. If you happen to live in Austria, you probably now what that means. See most Austrian summer breaks for students last from June till the beginning of September while Christmas lasts from December till January. There is also one small break during November. You can clearly see that this could be a chat between friends who happen to be students but don’t have the same classes together. Those friends probably spend a lot of their free time together, which explains the lack of data during the breaks.
