Runedate

The Runedate was introduced with the creation of the minigame Player-owned Port. It is shown on the pop up interface when reading the Captain's log.

The Runedate is an obvious reference to the science fiction series Star trek, where the captains of the star ships also had a captain's log with an according stardate.

The Runedate is an increasing decimal number. which shows the elapsed number of days since jagex released their membership service for Runescape, which was released on February 27th, 2002.
