Initially, stardates varied wildly and were not necessarily sequential, though they generally increased over time.<ref name="TOS1"/><ref name="TOS2"/><ref name="TOS3"/><ref name="TAS1"/><ref name="TAS2"/> This system remained in use until the 24th century.<ref name="TNG101"/>

In [[2322]],<ref name="TNG101"/><ref name="TNG126"/> a new stardate system was introduced. This adjusted the previous system by having 1000 stardates be equivalent to one [[Earth]] [[year]], but remained otherwise independent from the Earth calendar. Each stardate was approximately 8 [[hours]], 45 [[minutes]] long, and was subdivided by a decimal; the number of digits following the decimal point could be used to calculate the precise time with great detail. The first day of each "stardate year" (when Stardate x999 becomes Stardate y000, where x and y represent the current "stardate years," e.g. 51999 and 52000) fell on 23 May of each Earth year; the [[First Contact Day]] holiday fell on Stardate x868 of each year (e.g. Stardate 54868.6 was [[2377#APR05|5 April 2377]]).<ref name="VOY269"/><ref name="NextGen"/>

<ref name="NextGen">The new stardate system introduced in ''[[Star Trek: The Next Generation]]'' followed much clearer rules than that of the original series. Each year was divided into 1000 stardates, and the Earth year 2364 was given in the season 1 finale, "[[The Neutral Zone (Episode)|The Neutral Zone]];" this was the first time an Earth calendar year was mentioned on screen. It was not until "[[Homestead (Episode)|Homestead]]," in the seventh season of ''[[Star Trek: Voyager]],'' when both an Earth date (First Contact Day, e.g., 5 April 2377) and a stardate (54868.6) were given in the same episode. This allows for a very precise calculation of which Earth dates align with a stardate.</ref>
