For the third time in two years, Mayor Bloomberg has announced that he intends to end a program that provides after-school day-care vouchers to 2,200 Orthodox Jewish families in Brooklyn at a cost of $1 million a month.

Officials said yesterday that letters have gone out notifying the families that the program — begun under the Giuliani administration 13 years ago — will expire on Dec. 31.

But a group of five City Council members, led by David Greenfield (D-Brooklyn), has asked for a meeting with the mayor to seek a last-minute reprieve.

Bloomberg has tried to cut the program several times before, only to grant one delay after another, including in 2009 when he was up for re-election and seeking support from the Orthodox Jewish community.

Greenfield said kids in the program are aging out at the rate of 20 percent a year, so the city’s cost is diminishing every year, since no new vouchers are being issued.
