ccf-deadlines

ccf-deadlines answers the question every computer science researcher keeps asking: when is the next paper deadline? It's a community-maintained list of CS conference deadlines, from NeurIPS and ICML to database, networking and security venues, with each one's timezone, rank and past dates. MIT licensed, free, no account needed.

Most people have nothing to install. Browse ccfddl.com, or subscribe to an iCal feed filtered by field or rank so deadlines land in your own calendar. There's also a free public MCP server so an AI assistant can look deadlines up directly, and a Python CLI you install from source. Updates arrive as pull requests, and the maintainers use AI agent skills to check each change against the official call for papers. Grad students, researchers and anyone planning submissions should bookmark it. The older paperswithcode/ai-deadlines site went quiet in 2024 and only covered AI; this covers all of CS and gets updated constantly.

The catch: the ranking system is China's CCF list, so the A, B and C badges reflect that list's view of each venue. CORE rankings are there as a filter, but secondary. And when a conference doesn't publish a time or timezone, the site fills in 23:59 Anywhere on Earth by convention, so check the official call before you plan around the last hour.
