There will be four online mirror contests during the camp. ↵
↵
- day1 : [Mar. 20 (00:30 — 05:30 GMT)](https://www.timeanddate.com/worldclock/fixedtime.html?day=20&month=3&year=2017&hour=00&min=30&sec=00)↵
- day2 : [Mar. 21 (00:30 — 05:30 GMT)](https://www.timeanddate.com/worldclock/fixedtime.html?day=21&month=3&year=2017&hour=00&min=30&sec=00)↵

The contest duration is 5 hours and there are 3 to 4 problems in each day. Problem statements will be provided both in Japanese and English this year.↵

↵
Good luck and have fun!↵

**UPD1:**↵
↵
We will use [CMS](https://cms-dev.github.io/) (customized version) on our server to hold the contests. The registration URL will be announced just before the first contest.↵
↵
Providing English statements is our first trial for this year, so there aren't past English problems. If you try past problems with Google Translate, you can get them from [here](https://www.ioi-jp.org/camp/index.html).
