World Time Zones
The world is divided into 24 time zones, each roughly 15° of longitude wide. UTC (Coordinated Universal Time) is the reference point. Some countries span multiple time zones (like the US with 6), while others use a single zone (like China).
Daylight Saving Time
Many regions adjust clocks forward 1 hour in spring (DST) and back in autumn. This affects time zone offsets: EST becomes EDT (UTC-4), PST becomes PDT (UTC-7). Always check if DST is in effect for accurate conversions.
Time Zone Conversion
CalcSolver's time zone converter handles time calculations across any two time zones, including daylight saving time (DST) adjustments. Enter a time in one zone and instantly see the corresponding time in another — essential for international meetings, travel planning, and global team coordination.
9:00 AM in New York (EST UTC-5) = 2:00 PM in London (GMT UTC+0) = 10:00 PM in Tokyo (JST UTC+9). During US summer (EDT UTC-4), that same 9:00 AM New York becomes 3:00 PM London. DST shifts are the most common source of scheduling errors.
Meeting planning tip: for teams spanning UTC-8 to UTC+8, the overlap window is typically 8:00-10:00 AM PST / 4:00-6:00 PM GMT / midnight-2:00 AM JST. Always confirm DST status for both locations when scheduling — transitions happen on different dates in different countries. Use CalcSolver's time calculator for simple time arithmetic.
