Seventh of Adar

[3] The Biblical sources suggesting these dates are as follows: Joshua crossed the River Jordan on the 10th of Nisan.

[7] Assuming that the Divine command immediately followed the end of the mourning period, Moses must have died 30 days before 7 Nisan, i.e. 7 Adar.

The Seventh of Adar is a fast day in some Jewish communities.

[2] In Israel, the Seventh of Adar is designated as a day in remembrance of those soldiers who have fallen in war, but whose bodies have not been found or identified, in reference to the Biblical verse noting that no one knows the exact burial place of Moses "even to this day".

[8] On Mount Herzl, there is a wall with the names of 588 fallen soldiers who died in Israel with unknown grave sites.
