Not in the desert.

Not in the desert.
The date of Chanukah (25 Kislev) has an affinity for the idea of renewal. This is evidenced from the fact that in the desert the Mishkan (tabernacle) was completed on 25 Kislev 2449. But it’s construction and use was postponed until (the end of Adar and) Nissan of that year. This date was not celebrated until the Chanuka story again exposed this day’s uniqueness. Why not celebrate this date from the time of the Mishkan?
