"Jewish Arbor day" would be 'Tu B'Shevat' (the 15th day of the Hebrew month of Shevat), the new year for the purpose of calculating the age of trees for tithing.
It's celebration is informal, usually eating new fruit (anyone remember 'bukser'?) and raising money for or actually planting trees.
If it does not fall on a Sabbath, I know of no reason why guitar-playing wouldn't be OK.
It fell on Feb. 3/4 this year.
Thanks for the info. IMO guitar music is never appropriate for religious services!
And did you notice the major league sign that took place that night? (The Jewish day begins in the evening).
The moon hit full, hours later it passed 0.9 degrees north of Saturn (which is in Leo). Several hours later it passed 1.1 degrees north of Regulus (the heart of the lion).
Anything less than a 1 degree separation is considered a conjunction. Down here on earth its called conception. Noticing this I pulled out my Hebrew calendar and nine months from Tu B’Shevat falls right into Sukkot!
What will be born?
And if that’s not enough, the lunar eclipse falls out on Purim. No coincidences here!

Joel 2
31 The sun will be turned to darkness and the moon to blood before the coming of the great and dreadful day of the LORD.
As always there’s lots more.
Shabbat Shalom!
