Dhaka and Zulu overview
City routeDhaka local time is 6 hours ahead of Zulu. To convert Dhaka time to Zulu, you subtract 6 hours from the local reading. For example, when it is 15:00 (3:00 PM) in Dhaka, Zulu time is 09:00. At midnight (00:00) in Dhaka, Zulu reads 18:00. This 6 hours gap applies during the entire year since Dhaka does not observe DST.
