📡 DDL Radar · CS Conference Deadline Tracker

Track submission deadlines for ~70 conferences across 16 CS areas — with the personal features the big trackers lack: favorites, calendar export, historical deadline patterns and abstract-deadline warnings.

Live demo → yzyhhhstudy.github.io/paper-deadlines

Inspired by ccfddl and aideadlin.es; differentiated by personalization and calendar integration.

Features

• ⏳ Live countdowns (days/hours/minutes), red under 7 days, orange under 30
• 🗂 ~70 conferences in 16 areas — AI/ML, CV, NLP, Speech, Robotics, Data Mining, DB, Systems, Arch/HPC, Networking, Security, SE, HCI, Graphics, Theory, Multimedia — plus 📖 rolling journals (TPAMI, IJCV, JMLR, TACL)
• 📱 Installable PWA: works offline, add to home screen / desktop
• 🔔 Deadline notifications: browser reminders 7 days / 1 day before starred deadlines
• ☰ Timeline view: deadlines grouped by month, next to the classic card grid
• 🔗 Shareable URLs: every filter/search/view choice is encoded in the address bar
• 🔎 Alias-aware search (NIPS → NeurIPS, Oakland → IEEE S&P, ESEC/FSE → FSE…)
• 📊 h5-index & acceptance-rate tags for ~36 major venues, sortable by either
• ⚠️ Abstract-deadline aware: when a conference has an earlier abstract deadline, the countdown targets it and warns you — never mistake the full-paper date for your real DDL
• 📈 5-year historical deadlines for 20 major venues — see each conference's annual pattern at a glance
• 🌏 7-language UI (English / 中文 / 日本語 / 한국어 / Deutsch / Français / Español) — auto-detected, remembered locally
• 🏷 Multi-select filters by area and rank, plus full-text search
• 📋 Submission pipeline: drag cards across Planned / Writing / Submitted / Rebuttal / Accepted / Rejected on the kanban Board, with your personal hit-rate stat
• 📈 Detail view: click any card for key dates (incl. rebuttal & notification countdowns) and an acceptance-rate trend chart
• ⇥ Timeline view: horizontal time axis with 3/6/12-month zoom (overlapping deadlines stack into lanes) plus a list mode
• 🚀 Submit-portal links straight to OpenReview/ARR where available
• 🔔 Reminders with custom lead times (1/3/7/14/30 days); sort by deadline, h5, or acceptance rate in either direction
• 🎓 Dual rank system: the English UI shows CORE ranks (A*/A/B/C — the international standard), while the Chinese UI shows CCF ranks (China's official venue tiers)
• ⭐ Star conferences (persisted locally), one-click .ics export of starred deadlines (abstract + full paper, with 7-day-before alarms) for Google/Apple Calendar
• 📡 webcal:// subscription — subscribe once (all conferences, or per area) in Google/Apple Calendar and deadline updates sync automatically
• 🌐 Deadlines auto-converted to your local time (source data stores official timezone, mostly AoE)
• 🎨 Dark / light / auto (system) theme

📡 Calendar subscription

Click Subscribe in the header, or add a webcal:// feed directly in Google/Apple Calendar — webcal://yzyhhhstudy.github.io/paper-deadlines/feeds/all.ics for everything, or a per-area feed like feeds/ai-ml.ics. Feeds regenerate automatically whenever the data changes, and your calendar app re-syncs them on its own — no manual re-export.

🗂 Data & contributing

Deadlines are estimates extrapolated from past cycles — always verify against the official site before submitting. One YAML file per conference under data/conferences/:

name: "ICLR"
fullName: "International Conference on Learning Representations"
area: "AI/ML"
ccf: "CCF-A"    # CCF-A / CCF-B / CCF-C / Non-CCF (Chinese UI)
core: "A*"      # CORE: A* / A / B / C / Unranked (English UI)
link: "https://iclr.cc"
editions:
  - id: "ICLR 2027"
    abstractDeadline: "2026-09-18T23:59:59-12:00"   # optional
    deadline: "2026-09-24T23:59:59-12:00"           # AoE = -12:00
    confDate: "2027-04"
    place: "TBD"
history:        # past full-paper deadlines (optional)
  - "2025-09-19"

Spotted an outdated deadline? Edit the YAML and open a PR — CI validates the format, and after merge it rebuilds data.js and the calendar feeds automatically. To build locally: npm install && npm run build (the page itself stays a zero-dependency static site; data.js, data.json and feeds/ are generated, don't edit them by hand).

Optional YAML fields: aliases (search synonyms), h5, acceptRate, type: journal + rolling: true for journals without fixed deadlines.

• Read-only API: all data is published at /data.json — build your own client (CLI, extension, bot) on top of it.
• Weekly reconciliation bot: an Action cross-checks our dates against ccfddl every Monday and opens an issue listing any differences.
