Most of North America is in Daylight Saving Time until 2am October 26.
The places in North America which are not, are Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands, the Eastern Time Zone portion of the State of Indiana, and the state of Arizona (not the Navajo Indian Reservation, which does observe).
So for the majority - 6pm EST (5pm CST, 4pm PST) would be 7pm EDT, 6pm CDT, and 5pm PDT.
