Câu hỏi thường gặp

Timezone Converter là gì?

A Timezone Converter is a tool that maps a date and time in one IANA timezone (for example, "America/New_York") to its equivalent moment in another (for example, "Asia/Tokyo"). DST-aware converters apply the correct offset for the chosen day, including the spring-forward and fall-back transitions. Multi-city comparison lets meeting planners see one moment across every participant's wall clock.
