Lunar Essence Question

Will the lunar essence roll over from event to event or will it be a clean slate each time?

Also will the event last ~three days like the full moon irl?

From the News post:

"Note: Lunar Essence carries over if it is unused.  If you end the day with 50 Lunar Essence, upon rollover, you will have 75 Lunar Essence (50 + the 25 bonus from rolling over).  Carried-over Lunar Essence does not impact the 100 you can earn from exploring"

And about how long it is:

"This will be a week-long mini event that reoccurs every single month.  We are a little late with launching it for February, but in future it will begin on the third Friday of every month and last until 11:59pm the following Thursday."

OK, does that include like month-to-month roll over and not just day-to-day?
