🌏 Timezone Converter

📖 How to Use

1. Choose the departure timezone in the "From City" dropdown, e.g. Taipei.
2. Enter the local time in that city in the "Time" field — it's pre-filled with your current system time when the page loads, and you can edit it freely.
3. Choose the destination timezone in the "To City" dropdown, e.g. New York.
4. The result updates instantly as soon as any of the three fields changes — there's no button to click.
5. The large number shows the converted time and destination city. The smaller line underneath tells you whether that time falls on the "same day," "days later," or "days earlier" than the source city — handy for spotting whether a meeting time actually lands on the day you expect.
