Do the International Date Line and Arctic Circle Intersect?

No. The International Date Line (IDL) and the Arctic Circle (66°33′N) do not intersect.

• Arctic Circle – Fixed latitude circle at ~66.5°N.
• International Date Line – Zigzags along ~180° longitude, deviating to avoid splitting nations (e.g., around Russia’s Chukotka, Aleutians, Kiribati).

The IDL passes through the Bering Strait (between Russia and Alaska) at ~65°–66°N—just south of the Arctic Circle. It then jogs east to keep all of Russia’s territory west of the line, and all of Alaska east. Thus, the two lines approach closely but never cross.
