The Time of Remembrance and Reconciliation for Those Who Lost Their Lives During the Second World War is observed annually from May 8-9. These dates commemorate:
- May 8: Victory in Europe Day (Germany's surrender in 1945)
- May 9: Victory Day observed in Russia and some post-Soviet states
The UN-established observance honors all casualties while promoting reconciliation. While WWII events occurred throughout the year, May is internationally recognized for this specific remembrance period.
Thus, the correct answer is (2) May.
