Global E-Commerce Sale Time Zones

Singles' Day, Black Friday, Prime Day — local midnight vs global UTC.

Global sale "midnight launches" use **local midnight in each anchor market**, not one UTC instant worldwide. Singles' Day starts 00:00 Asia/Shanghai on 11 Nov; US Black Friday online often tracks US Eastern or Pacific calendar days. Wrong platform time zones can end deals hours early or late.

Common anchors

  • Singles' Day / 618: Asia/Shanghai local 00:00
  • US Black Friday / Cyber Monday: US local calendar
  • Amazon Prime Day: per marketplace local time
  • EU seasonal sales: CET/CEST local midnight or 8 AM

Ops checklist

  • Verify admin engine zone vs customer-facing zone
  • Support macros: full phrase "ends 11:59 PM America/New_York"
  • DST weeks: validate with Convert
  • Multi-column comms: Global Live Events and Launch Times

Regions: China Time Zone: Beijing Time Nationwide, United States Time Zones Guide, European Time Zones and DST.
