Compare airport locations
Compare codes, geography and time-zone identifiers for two airports. The calculator measures geographic separation, not flight time or ground-transfer feasibility.
Great-circle distance : ≈ 2437 km
Distances are calculated between airport reference coordinates on a sphere of radius 6,371 km, rounded to the nearest kilometre. They are not road distances, flight lengths or evidence of a scheduled service. This selection is limited to airports in our reference.
| Airport | O. R. Tambo International Airport | Julius Nyerere International Airport |

| Code | JNB / FAOR | DAR / HTDA |
| Location | Johannesburg | Dar es Salaam |
| Country | South Africa | Tanzania |
| Time zone | Africa/Johannesburg | Africa/Dar_es_Salaam |
| Field elevation | 5558 ft · ≈ 1694 m | 182 ft · ≈ 55 m |
Reading the time zone
Use the IANA identifier with the exact travel date. A fixed UTC offset is not reliable across daylight-saving changes or government decisions. Timetables normally show local times at each airport; compare complete dates as well as hours when crossing midnight or the international date line.
Geography: OurAirports, public domain. Names, codes and coordinates are reference data, not operational navigation information. Time-zone identifiers: IANA conventions.
Practical reading
- Airport codes and time zones: read an international itinerary
Avoid confusing city codes, airport identifiers, local dates and UTC weather timestamps.
- Terminal transfers: airside, landside and airport changes
A terminal change and an airport change involve different journeys.
- Separate tickets and self-transfer: the checks before booking
Compare the whole transfer process and recovery options, not only the advertised connection time.
