What date was showing by the spaceship that crashes into a lake at the beginning of the 1968 film "Planet of the Apes"?

"Planet of the Apes" is a 1968 American science fiction film directed by Franklin J. Schaffner. It stars Charlton Heston, Roddy McDowall, Kim Hunter, Maurice Evans, James Whitmore, James Daly and Linda Harrison. The screenplay by Michael Wilson and Rod Serling was loosely based on the 1963 French novel "La Planète des Singes" by Pierre Boulle. Jerry Goldsmith composed the groundbreaking avant-garde score. It was the first in a series of five films made between 1968 and 1973, all produced by Arthur P. Jacobs and released by 20th Century Fox.

Astronauts Taylor (Charlton Heston), Landon (Robert Gunner) and Dodge (Jeff Burton) are in deep hibernation when their spaceship crashes in a lake on an unknown planet after a long near-light speed voyage, during which they aged 18 months due to time dilation while their fourth crewmate Stewart died and decayed due to a malfunction. The three survivors abandon ship when it immediately starts sinking, Taylor remaining on long enough to see the date is November 25, 3978, approximately two millennia after their departure in 1972. Once ashore, Dodge performs a soil test and pronounces the soil incapable of sustaining life.
