The Ages of Tkon were eras of the Tkon Empire as marked by the galactic motionary star time charts. The Ages were set chronological periods with fixed dates. As such, the Tkon reckoned time by the current Age and the time to other Ages in the past or future similar to the reckoning of time by centuries.

Little is known of the number of Ages, their relative lengths, or their order. Ages of Tkon are divided into periods known as baktun, but the exact period of a baktun is unknown. It is known that it was during the Age of Makto over 600,000 years ago that the central star of the Empire went supernova, heralding the eventual collapse of Tkon.

The portal encountered by the USS Enterprise-D in 2364 in the Delphi Ardu system was last active during the Age of Bastu. (TNG: "The Last Outpost")
