What is special about Sivan 20?

Tach v'Tat" (Hebrew: גזירות ת"ח ות"ט, lit. Decrees of 5408 and 5409) is the Jewish historical term for the devastating Cossack massacres that ravaged Polish, Lithuanian, and Ukrainian Jewry in 1648 and 1649. It is considered one of the bloodiest chapters in Jewish history preceding the Holocaust.

While the violence raged across multiple months, the historical date designated to commemorate the tragedy is the 20th of Sivan (כ' בסיון). 

• The Historical Trigger: On the 20th of Sivan, 5408 (June 10, 1648), one of the first major and most brutal large-scale massacres of the uprising took place in the town of Nemyriv (modern-day Ukraine), where thousands of Jews were murdered
