Himalaya mountains are actually a system of many mountains and each of them formed in different time range. According to information I found on Internet (=P), they were formed between 60-80 million years ago.
Mt. Everest is one of the youngest among them because it was formed 60 million years ago.
Himalaya mountains was formed by the collision of the India(Indo-Australian) Plate and the Chinese(Eurasian) Plate. Until Today, Himalaya Mountains are still growing because India Plate continuously moves 3-5 cm NNE per year.

before 120 million years the sea floor of tethian sea up lifted to reach this much height of himalayan .
in the paleozoic era and devonian epoch about 360 to 410 million years ago the continents have separated .so you can say himalay is 120 million years old

I believe they are about 50 Million Years Old.

The Himalaya are among the youngest mountain ranges on the planet. According to the modern theory of plate tectonics, their formation is a result of a continental collision or orogeny along the convergent boundary between the Indo-Australian Plate and the Eurasian Plate. The collision began in the Upper Cretaceous period about 70 million years ago, when the north-moving Indo-Australian Plate, moving at about 15 cm/year, collided with the Eurasian Plate. By about 50 million years ago this fast moving Indo-Australian plate had completely closed the Tethys Ocean, whose existence has been determined by sedimentary rocks settled on the ocean floor and the volcanoes that fringed its edges. Since these sediments were light, they crumpled into mountain ranges rather than sinking to the floor. The Indo-Australian plate continues to be driven horizontally below the Tibetan plateau, which forces the plateau to move upwards. The Arakan Yoma highlands in Myanmar and the Andaman and Nicobar Islands in the Bay of Bengal were also formed as a result of this collision.

The Indo-Australian plate is still moving at 67 mm/year, and over the next 10 million years it will travel about 1,500 km into Asia. About 2 cm/year of the India-Asia convergence is absorbed by thrusting along the Himalaya southern front. This leads to the Himalaya rising by about 5 mm/year, making them geologically active. The movement of the Indian plate into the Asian plate also makes this region seismically active, leading to earthquakes from time to time.
