Soooo yeah, quick question, does Merana has specific dates she appears on or is she a random event that happens once in a year? I need to change one of my pets with her quest. Thanks

it's random, but it's not as infrequent as once a year! the time between her appearances varies but it's usually a couple of weeks or so.

I see! thank you. Do we get an announcement when Merana appears?

This group gets pinged when she appears: xxx

I feel like I see her multiple times a week, so you probably don't have to wait as long as you think.

No there's no announcement for it one of best ways is for you to stalk the world map
