ORDERED that the order is affirmed, without costs or disbursements.
The father contends that he is entitled to a downward modification of his child support obligation retroactive to the date on which one of the parties' children joined the armed services. However, the father may only be granted a downward modification of his child support obligation retroactive to January 3, 2000, which was the date of his application (see, Weitz v. Weitz, 1 A.D.2d 1025).
The father's remaining contentions are without merit.
