Recently, several people on the Runescape forums have asked how to find out the date that they started playing. The best answer we can give is to ask Hans in Lumbridge how many days until the player gets the 5 or 10 year veterans cape, and work it out from that. Then I remembered TipIt's great set of calculators, and thought what a good addition a calculator to work out when a player started playing from Hans's answer would be. Shouldn't be too difficult to code - subtract Hans's answer from days in 5 or 10 years, convert to seconds, subtract from current Unix time, then convert new Unix time back to a date.
