Time in Countries Worldwide

Time Zones by Country

Understanding time zones by country is essential for international communication, business, and travel. While some countries like China use a single time zone despite their large size, others like Russia span 11 time zones. The United States uses 6 time zones, while most European countries use just one or two.

Countries with Multiple Time Zones

Several countries span multiple time zones due to their geographic size:

• Russia - 11 time zones (most in the world)
• United States - 6 time zones (including Alaska and Hawaii)
• Canada - 6 time zones
• Australia - 3 main time zones
• Brazil - 4 time zones

Countries with Single Time Zones

Some large countries choose to use a single time zone for national unity:

• China - Uses Beijing Time (UTC+8) across the entire country
• India - Uses IST (UTC+5:30) throughout

Daylight Saving Time by Country

Daylight saving time practices vary significantly by country. Most of Europe and North America observe DST, while most of Asia, Africa, and South America do not. Some countries have recently abolished DST, including Russia (2011), Turkey (2016), and Brazil (2019).
