My 2018 Lag B'Omer post is here. Follow the links there for the biblical and rabbinic background of the holiday and collected previous posts of interest. I missed Lag B'Omer 2019, due to circumstances beyond my control. But there are additional posts on the subject here, here, and here.
Like everything else, the observation of Lag B'Omer has been affected by the coronavirus. Normally a crowd of up to five-hundred-thousand people celebrate with bonfires on Mount Meron. But this year the observations are massively scaled down.
If you are celebrating, however you go about it, please celebrate safely!
