Double XP Weekend

Bonus XP Weekends are events where players receive bonus experience when training skills. Bonus XP Weekends start on a Friday and end on the next Monday. The bonus experience is gained when performing most normal training activities, but does not apply to things like quest rewards, random event rewards, or D&D rewards. The experience rate during a Bonus XP Weekend is up to 2.7 times higher than normal. The amount of bonus experience decreases over a period of 10 hours, down to just 1.1 times the normal amount. Although Jagex has indicated that non-members may be able to participate in the future, these events have been members only thus far. Many players choose to gather as many skill training supplies as they can in the days leading up to a Bonus XP Weekend, so they can train their skills during the weekend. This causes the price of a lot of supplies to rise during that period. When the Bonus XP Weekend is over, the price of those supplies will go down to their former level again.

Events
To date, Jagex has released two Bonus XP Weekends:
 * /March 2010/
 * /September 2010/

Trivia

 * It has been confirmed there will be future Bonus XP Weekends. They may be opened up to free players, but Jagex has yet to make that decision.
 * The first Bonus XP Weekend showed the first appearance of the XP Counter, located next to the minimap. The XP Counter was later released to all players on 12 April 2010.
 * If you started your Bonus XP Weekend and your membership runs out and you renew it, your counter will be reset to 2.7x.
 * Summoning gave 2.7x experience for the first weekend only, thereafter it only gives 10% more than normal. This is due to the bulk of the work being in the collecting of the charms rather than training the skill itself.
