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 Jōetsu to Shanghai?

The hourly table for Jōetsu and Shanghai lists corresponding local times for each hour and marks the same instant and any date rollover.
