How many days to unstake zil?

Excuse me, I'm a bit confused about the unstaking process for ZIL. Could you clarify for me how many days it typically takes to unstake ZIL? I've heard that there's a locking period involved, but I'm not entirely sure how long it lasts. I'm considering unstaking some of my ZIL holdings but would like to have a clear understanding of the timeline involved before I proceed. Could you provide me with a rough estimate or the exact number of days if possible? Your assistance in this matter would be greatly appreciated.
