Frequently Asked Questions
What is the time difference between EDT and WIB?
During standard time, Western Indonesian Time is 11 hours ahead of Eastern Daylight Time.
When does EDT start and end?
EDT begins on the second Sunday in March at 02:00 local time, when clocks spring forward one hour from EST (UTC-5) to EDT (UTC-4). It ends on the first Sunday in November at 02:00 local time, when clocks fall back to EST. In 2026, EDT runs from March 8 through November 1.
Is EDT the same as EST?
EDT and EST are two phases of the same Eastern Time zone, not two separate zones. EST (Eastern Standard Time) is the winter offset at UTC-5, observed from early November through mid-March. EDT (Eastern Daylight Time) is the summer offset at UTC-4, active during Daylight Saving Time — meaning New York and Toronto run one hour ahead of their winter clock for roughly eight months of every year.
Does Indonesia observe Daylight Saving Time?
Indonesia does not observe Daylight Saving Time and has not done so since 1963. WIB remains fixed at UTC+07:00 year-round, providing consistent, predictable scheduling for businesses and travelers operating across Indonesian time zones.
Which areas of Indonesia use WIB?
WIB applies to Indonesia's westernmost islands: Sumatra, Java, West Kalimantan, and Central Kalimantan. These regions encompass the country's largest population centers and its political and economic capital, Jakarta.
