On 23rd june codeforces round is colliding with a rated contest in codechef. On 30th june again another codeforces contest is colliding with codechef lunchtime. Is it possible that the timings might be slightly changed that they don't collide? I'm sure many participants would like to give both contests and don't want to choose between the 2 especially since it is summer vacation and most of us has lot of free time.
upd: So the issue has been resolved 23rd codechef contest will be shifted by a day. 30th codeforces contest time will be adjusted.
