What is held to be the earliest date range for the 13 upanishads in oral form?

The earliest Upanishads, often called the "principal" or "primary" Upanishads, are generally dated in their oral form to approximately 800-500 BCE, though some scholars push certain texts even earlier.

The chronological grouping typically looks like this:

Earliest group (circa 800-600 BCE):

Brihadaranyaka Upanishad
Chandogya Upanishad
These two are considered the oldest and are associated with the late Vedic Brahmana texts.

Second group (circa 600-500 BCE):

Taittiriya Upanishad
Aitareya Upanishad
Kaushitaki Upanishad
Kena Upanishad

Third group (circa 500-400 BCE or slightly later):

Katha Upanishad
Isha Upanishad
Svetasvatara Upanishad
Mundaka Upanishad
Prashna Upanishad
Mandukya Upanishad
Maitri Upanishad

The dating is based on linguistic analysis, philosophical development, and references within the texts themselves. It's important to note that these texts existed in oral tradition for generations before being written down, so the "oral form" dates precede any written manuscripts by centuries. Scholars also debate these dates, with some proposing earlier dates for the oldest Upanishads (as early as 900-800 BCE) and others being more conservative.
