Codeforces Contest Schedule and Frequency 2026

Codeforces is the most popular competitive programming platform in the world, hosting contests almost every week. If you have been searching for how often Codeforces contests happen or the Codeforces upcoming contests 2026 schedule, this guide covers everything.

How Often Are Codeforces Contests?

Codeforces typically hosts 2-3 contests per week. Unlike LeetCode's fixed schedule, Codeforces contests are announced a few days in advance and do not follow a strict recurring pattern. This is why having a reminder tool is essential.

Types of Codeforces Rounds

Div 1 (1900+ rated) For expert-level competitive programmers. Features extremely challenging problems. Happens a few times per month, often combined with Div 2 as "Div 1 + Div 2" rounds.

Div 2 (0-2100 rated) The most common Codeforces round. Usually 5-6 problems, 2 hours long. Happens multiple times per week. This is where most competitors build their rating.

Div 3 (0-1600 rated) Beginner-friendly with 7 problems over 2 hours 15 minutes. Great for newcomers. Happens 1-2 times per month.

Div 4 (0-1400 rated) The easiest tier, with 8 problems designed for absolute beginners. Relatively rare but excellent for getting started.

Educational Rounds (0-2100 rated) Educational rounds focus on teaching specific algorithms and data structures. They run for 2 hours with 6-7 problems and have an extended 12-hour hacking phase afterward.

Global Rounds Open to all ratings, with larger prize pools. Happen a few times per year and are some of the most competitive events on the platform.

When Do Codeforces Contests Start?

Most Codeforces contests start at 11:35 UTC or 14:35 UTC (14:35 or 17:35 Moscow time). However, this varies. Some contests run at unusual times to accommodate Asian or American time zones.

This unpredictability is precisely why relying on manual checking is unreliable. The Contest Reminder extension pulls the schedule directly from the Codeforces API and syncs it to your calendar automatically.

Codeforces vs LeetCode: Which to Focus On?

  • Codeforces is better for competitive programming skill-building and algorithmic depth
  • LeetCode is better for software engineering interview preparation
  • Both are useful for a well-rounded programmer

The ideal strategy? Do LeetCode daily challenges on weekdays and Codeforces rounds on weekends. Use the Contest Reminder extension to track both without switching between tabs.

How to Track Codeforces Upcoming Contests

  1. Check codeforces.com/contests manually (unreliable, easy to forget)
  2. Subscribe to Codeforces notifications in your profile settings
  3. Use Contest Reminder to get automatic calendar sync and browser notifications before every round

The difference between a 1400-rated and an 1800-rated programmer is often just consistency. Show up to every round, upsolve afterward, and the rating will follow.
