Imam Talib Abdur-Rashid said Mayor Michael R. Bloomberg should reconsider his opposition to the school holidays. “It’s an election year,” he said.

Spurred by a broad coalition of religious, labor and immigrant groups, the City Council overwhelmingly passed a resolution on Tuesday to add two of the most important Muslim holy days to the public schools’ holiday calendar.

But the vote, which was nonbinding, put the Council in conflict with Mayor Michael R. Bloomberg, who has the final say to designate the days off and has said he is resolutely opposed to the idea.

The mayor told reporters before the vote that not all religions could be accommodated on the holiday schedule, only those with “a very large number of kids who practice.”

The current school calendar recognizes major Christian and Jewish holy days like Christmas and Yom Kippur, but no Muslim holy days.
