One lane = one conference (’26 + ’27 editions) Abstract deadline — open Abstract — closed / set Abstract — estimated (from last year) Today Pill = meeting (click to open) 📅 = add that conference’s dates to your calendar

Dates compiled from official conference and society websites and verified 6 Jun 2026. Where a 2027 abstract deadline isn’t posted yet, the timeline and table show an estimated deadline (dashed diamond, “≈ / Est.”) derived from that conference’s most recent verified deadline — these recur at about the same point each year, but confirm the exact date on the official site once announced. A few 2027 editions (ASH, SOHO, IMS, ESH-CML, ESMO GI/IO) haven’t announced meeting dates yet and appear with their current edition only. Educational study aid — verify every date before acting.
