BlizzCon takes place over two days and will cover all Blizzard games. Find more information on the BlizzCon website, including the schedule and virtual tickets.

The times for this release haven't been announced - it will likely deploy at some time in the early evening BST/early morning PST.

Mad King Thorn comes to Lion's Arch. Events include:

• The Mad King's Clock Tower (the hardest jumping puzzle in Guild Wars 2)
• The Mad Kings Realm
• Mad King Says
• The Ascent to Madness dungeon
• The ability to work on your Nightfury shoulder piece, which causes bats to fly around you
• Potentially something new that makes you look like a vampire

For one week only, there is a Rakghoul outbreak on Alderaan. Help contain this deadly virus and get:

• The Doctor Lokin companion (recruit a mad scientist who experiments on himself)
• Collect mounts, pets, armor and weapons

This in game event can be accessed via portals in Elwynn Forest and Mulgore. Pets, mounts, achievements and all sorts are available. You can also gain a boost to experience gain during the festival.

Less about the changing agricultural season then the name suggests, this holiday is about honoring the fallen. Not to be confused with Pilgrim's Bounty, which takes place in November. Will we see an expansion in this event this year, given the recent losses in Legion?

The Brewfest holiday event was one of the first added and involves lots of traditional dwarven pursuits - drinking, ram racing, drinking, fighting the Dark Iron, drinking, eating, drinking, invisible pets, drinking. There are mounts, pets and achievements available to enjoy. 

Visit Booty Bay to enjoy a mini-holiday to celebrate International Talk Like A Pirate Day. Arrrghhh!

Available for levels 15+, you can hunt down bounties for a variety of rewards including armor, weapons, pets and a mount.

Um. Yes. There are pets and a mount and ... the whole thing is crazy.

The Rising, the celebration of rememberance for Eorzea's fallen, is being disrupted by a missing person. Head to Ul'dah to help find them and get in game loot (pets, orchestrion rolls, etc.)

Earn both at 250%. A great opportunity to level a new character and experience the game's strongest content (its class stories).

The Lunar Festival is here. There are achievements to get, fires to start and put out and fireworks.

This micro-holiday celebrates the opening of the Gates of Ahn'Qiraj by gathering items to turn in. Only one Faction can win. Will it be yours?

The weekly bonus event this week is Wrath of the Lich King Timewalking. You'll be able to run:

• Ahn'kahet: The Old Kingdom
• Gundrak
• Halls of Lightning
• The Nexus
• Utgarde Pinnacle
• Pit of Saron

You'll receive badges and level-appropriate loot from bosses. Get a quest from Archmage Timear in Dalaran to also get a Seal of Broken Fate and a piece of gear from Normal Difficulty Nighthold.

Its New Year in Tyria and you can make lovely gold from those lucky envelopes, as well as playing a few games of Dragon Ball. Theres also a Rooster themed backpack to get.

Not sure on the final end date, but at a guess this will run for 2 weeks given Lunar New Year in on 28 January 2017.
