FAQ

How many hours apart are Hamhŭng and Tokyo right now?
For Hamhŭng and Tokyo, the current difference is 0, calculated from today’s time-zone rules. The page shows the local date in both cities on a 24-hour clock. Daylight-saving changes can alter the gap. Use specific-date mode for another day and check for a date rollover rather than carrying today’s offset forward. Verify the intended local date on each side before scheduling, especially when the conversion falls near midnight or the destination observes a different seasonal clock change.
Does the time difference between Hamhŭng and Tokyo stay constant all year?
The gap between Hamhŭng and Tokyo does not necessarily stay constant all year. If the two cities change daylight-saving time on different dates, their difference can vary; months 1 and 7 may show different results. Choose the intended date in specific-date mode and check the converted local date. Do not assume that 1 fixed offset applies for every day of the year, particularly when arranging future meetings or reviewing dates near seasonal clock changes.
How does the hourly table mark date changes and daylight-saving gaps from Hamhŭng to Tokyo?
The hourly table for Hamhŭng and Tokyo lists corresponding local times for each hour and marks the same instant and any date rollover. It covers 24 hourly slots across 2 cities; a local time skipped by a daylight-saving jump is identified instead of being invented. Check the date and the time zones on both sides when arranging a meeting. Shifting the displayed hour alone can give the wrong local date when the conversion crosses midnight.
