ty. xD

It is a good reference, though I do find some of the dates on there wrong.  For example, it lists the next 2x Ancients as being 22nd of June, but it should be the 22nd of July.  There are some older dates that are wrong too.  It is mostly right though

@pabloaraujo.nh the events run every 2 weeks, and cycle between ancients, void and sacred.  The last one was the 5th of September for 2x Sacred, so the next one will be 2 weeks after that at 19th September for 2x Void, and then 2nd of October for 2x Ancients.  From there it will cycle back to Sacreds 2 weeks later.

Yes sometimes they write wong. So i link other reference on Hellhades page, but there just show the next 2x dates. https://hellhades.com/ Just scrolling down a littlebit and there is.

"On Friday the 19th of August we are expecting a 2x Void Event 2x Void Summoning Event"

For what it's worth, I usually just keep track of it on my own google docs at too https://docs.google.com/spreadsheets/d/1oZ5V4PzxLsqVK_7CbLD6ORR93M4RdTqPqZ5-YuJpJks/.  There's a few other things I track too

Here's a nice video about this "when to pull" dilemma. All the math provided. Interesting to see that sometimes, it may be better NOT to pull in 2x, because you can farm more books during other spots. If that's more important to you.
