How many episodes does the original Neon Genesis Evangelion anime have?

How to get close to this number

Two cours, so around twenty-six — the same answer the scheduling grid gives for almost any single-season anime of the era. Once you know that Japanese television commissions in quarterly blocks, a very large fraction of anime episode-count questions collapse into arithmetic on the number thirteen.

The ending is the reason this particular count is famous, and it is a production story as much as an artistic one. The final two episodes turned abstract, and a feature film later provided a more conventional alternative — so the twenty-six-episode television run is only one version of how the story concludes. Counting episodes does not settle what the work is.

That multiplicity is common in this medium and worth expecting. Television runs, films, director's cuts and later rebuilds coexist, sometimes contradicting each other, and a franchise can have several official endings at once. A question about episode count therefore specifies the original series deliberately, because the broader work has no single length at all.
