You need to find the press releases. Bloomberg should have all of them.
E.g. the last press release was 11th May 2017:
FOMC sets tentative 2018 meeting schedule The Federal Open Market
Committee, the monetary policy-setting arm of the Federal Reserve, on
Thursday announced its tentative meeting schedule covering 2018 and
going into 2019.
The committee's two-day policy meetings are currently scheduled as
Jan. 30-31; March 20-21; May 1-2; June 12-13; July 31-Aug. 1; Sept.
25-26; Nov. 7-8; Dec. 18-19; and Jan. 29-30, 2019. The Federal Reserve
Board chair is scheduled to deliver quarterly news conferences
following the March, June, September and December meetings.
The FOMC next meets June 13-14, and four more times before the end of
the year: July 25-26, Sept. 19-20, Oct. 31-Nov. 1 and Dec. 12-13.
Following its policy-setting meeting earlier this month, the FOMC left
the federal funds target rate unchanged at a range of 0.75 to 1
percent, but it did indicate that it is on track for an interest rate
hike in June.
