Does it account for Daylight Saving Time?

Yes, our converter uses the IANA timezone database, which includes all current DST rules for every timezone in the world.

UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. All timezones are defined as offsets from UTC.

Can I compare multiple timezones at once?

Yes, you can add multiple cities or timezones and see the equivalent times side by side.

How many timezones are there in the world?

There are 38 distinct UTC offsets in use, ranging from UTC-12 to UTC+14. This includes half-hour (UTC+5:30 India, UTC+9:30 Australia) and 45-minute offsets (UTC+5:45 Nepal, UTC+8:45 Australia).

What is the International Date Line?

The International Date Line (IDL) runs roughly along the 180° meridian in the Pacific Ocean. When you cross it westward, you gain a day; crossing eastward, you lose a day.

Why do some timezones have 30 or 45 minute offsets?

Countries chose offsets that best matched their solar noon. India uses UTC+5:30 and Nepal uses UTC+5:45 because standard hourly offsets didn't align well with their geography.

Which country has the most timezones?

France has the most (12 timezones) due to overseas territories. Russia spans 11 timezones. The US has 6 (including Hawaii and Alaska).

Time Conversion Guide: Oslo to Brussels

Oslo runs on Central European Summer Time (CEST) at UTC+02:00, currently observing daylight saving time. Brussels runs on Central European Summer Time (CEST) at UTC+02:00, also currently on daylight saving time. That puts Oslo no time difference Brussels — a difference of +0h at the current offsets.

In practice, when it is 9:00 AM in Oslo it is 9:00 AM in Brussels. Midnight in Oslo is 12:00 AM in Brussels. Because both zones shift for daylight saving, the gap between them only changes during the few weeks each year when their transition dates differ.

Why people convert Oslo to Brussels time

Scheduling a call from Oslo to Brussels: a 10:00 AM start in Oslo lands at 10:00 AM in Brussels, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Oslo and Brussels are inside the 9-to-5 working day between 9:00 AM and 5:00 PM CEST time (9:00 AM–5:00 PM CEST). That is roughly 8 hours of usable overlap.
Booking travel or deliveries: tracking Brussels local time against Oslo keeps pickup windows and arrival estimates honest across the +0h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM CEST" is unambiguous; "3 PM" across a +0h gap is not.
Block 9:00 AM–5:00 PM CEST as the recurring meeting window if you work primarily from Oslo and need Brussels colleagues present.
Oslo: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the +0h gap.
Brussels: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local time.
