Which month of the year and day, is best to visit? That's not overcrowded? And you could truly enjoy your time at the museum?

Yeah I agree you should go during the week less busy

Not sure of month but find that during week (mon-thur) is less hectic.

Do not go during holidays, or school vacation time! Middle of the week is probably better. It takes time to go thru... ONE DAY I swear is not long enough. There is sooooo much to see 👀

I found Wednesday morning the least crowded time to visit ...no lines what so ever...and that was February 20th...so mid week... compared to the first time I went it as an hour wait just to get on the elevator down to the beginning of the exhibition timeline.
