How many hours is Tokyo ahead of Budapest?

Tokyo (JST, UTC+9) is 8 hours ahead of Budapest during Central European Time (CET, UTC+1) in winter, and 7 hours ahead during Central European Summer Time (CEST, UTC+2) in summer. Hungary observes DST; Japan does not.

Does Japan observe Daylight Saving Time?

No. Japan abolished Daylight Saving Time in 1952. JST is always UTC+9 year-round with no seasonal clock changes.

When does Budapest switch between CET and CEST?

Hungary moves clocks forward one hour on the last Sunday of March (to CEST, UTC+2) and back one hour on the last Sunday of October (to CET, UTC+1).

What are the business hours overlap between Tokyo and Budapest?

Tokyo business hours are roughly 09:00–18:00 JST. In winter that corresponds to 01:00–10:00 CET in Budapest — almost no overlap. In summer it is 02:00–11:00 CEST. Effective overlap requires one side to work early morning or late evening.

Is the clock accurate?

Yes, as long as your device clock is synchronized (most modern devices sync automatically via NTP). The timezone conversions use the IANA database built into your browser.

What time is it in Budapest when Tokyo is at noon?

When it is 12:00 noon in Tokyo, it is 04:00 CET in Budapest in winter (UTC+1) or 05:00 CEST in Budapest in summer (UTC+2).

Summary

This tool displays the live current time in both Tokyo, Japan (JST, UTC+9) and Budapest, Hungary (CET/CEST) simultaneously. The hour offset between the two cities changes seasonally because Hungary observes Daylight Saving Time while Japan does not — the gap is 8 hours in winter (CET, UTC+1) and 7 hours in summer (CEST, UTC+2). All times are read from your device clock and update every second.

How it works

Your device clock is read via the JavaScript Date API.
Tokyo time is computed using the IANA timezone identifier Asia/Tokyo (always UTC+9).
Budapest time is computed using Europe/Budapest, which switches between CET (UTC+1) in winter and CEST (UTC+2) in summer.
The offset is calculated by comparing the UTC offsets of both timezones at the current moment.
The display updates every second so both clocks stay live and accurate.
A visual indicator highlights whether Budapest is the same day, a day behind, or a day ahead of Tokyo.
