‘Thus did Moses. In accordance with all that Yahweh commanded him, so did he. And it came about in the first month in the second year, on the first day of the month, that the Dwellingplace was raised up.'
So Moses did exactly as he was commanded, and on the New Years Day the Dwellingplace was raised up and fully furnished and sanctified. The Israelites erected the Dwellingplace on the first day of the first month, almost exactly one year after the they left Egypt (Exodus 40:2; Exodus 40:17). This was about nine months after Israel had arrived at Mount Sinai (compare Exodus 19:1). The making of the Dwellingplace had taken less than six months, a sign of their genuine dedication and enthusiasm. What a great day it was that it was now ready.
