New York runs on Eastern Time (EST/EDT). It's the reference timezone for US business — Wall Street opens 9:30 AM ET (NYSE, NASDAQ), most US Fortune 500 anchor their internal clocks to ET regardless of headquarters. Multi-office US meeting invites default to "ET" in the timezone field. The city aligns with Toronto (same offset), sits 5 h behind London (winter) / 4 h behind (summer).
North America runs five continental-US timezones (Eastern, Central, Mountain, Pacific, Alaskan) plus Newfoundland (a 30-minute offset from Atlantic Time — one of the few 30-minute timezones outside Asia). DST is nearly universal (except Arizona, Hawaii, most of Saskatchewan) and runs March → November. Business scheduling defaults to Eastern for multi-office US corporations regardless of headquarters.
