It is a bit late to answer, but here comes the translation:
On Friday, the market closes at 3:15 PM Central Time (which is 45 minutes earlier than usual).
The market reopens on Sunday 5:00 PM Central Time. There is no separate trading day for Monday, May 26. The Monday session is considered part of Tuesday (CME has six double day sessions per year - for Martin-Luther-King Day, President's Day, Memorial Day, Independence Day, Labor Day and Thanksgiving - the holiday is not counted as a separate trading session, but settlement of the holiday trades is regrouped with the trades of the next regular working day).
On Memorial Day the market is halted from 12:00 PM Central Time to 5:00 PM Central Time (the trading floor is only open until noon). The market reopens after the technical break.
Tuesday is a regular trading day. All orders GTD (good till date) which have been entered on Sunday or Monday will continue to run until the regular close on Tuesday, as this is considered a single trading day. There is no close nor settlement price on Monday. Data feeds will show no daily data for Monday, although the exchange has been open on Monday.
