Which Two Countries Share a Time Zone? Germany and Japan

Correct answer: C. Germany and Japan

Both observe UTC+9 during standard time (Japan Standard Time / Central European Summer Time).

• Germany: CET (UTC+1) winter, CEST (UTC+2) summer.
• Japan: JST (UTC+9) year-round (no DST).

Thus they share UTC+9 only when Germany is on summer time (late March–late October). China (UTC+8), Australia (multiple zones), US/UK (UTC-5 to 0), Brazil (UTC-2 to -5), South Africa (UTC+2) do not match Germany-Japan alignment.
