The Chief Rabbinate Council recently decided that when the Hebrew calendar dates for Lag B'Omer and Jerusalem Day fall on Saturday night and Sunday, the observances should be delayed until Sunday evening to avoid preparations for the observances that would violate Shabbat. In a letter written to government officials, including Education Minister Gid'on Sa'ar, the council said that school holidays scheduled for those Sundays should be moved to Mondays.
One of the popular aspects of Lag B'Omer is the burning of bonfires. Last year, the date for the start of Lag B'Omer fell on Saturday night. This year the date for the start of Jerusalem Day falls on Saturday night.
