Nobody is keeping score. Waiting longer costs you nothing, and the party is not less valid in March than it would have been in January.
The two honest schools of thought
One camp waits until the house genuinely feels lived in: furniture placed, boxes gone, the spare room no longer a warehouse. Guests see the finished thing, and you are not apologising in every room. The other camp deliberately books it early and uses the date as a deadline, because a fixed evening in three weeks unpacks a house faster than good intentions ever have. Both work. Which one you are depends entirely on whether a deadline motivates you or ruins your month.
What actually constrains the date
Three practical things, and none of them is etiquette. Whether there is somewhere for people to sit. Whether the kitchen can produce food and drink for the number you have in mind. And, if the garden or a particular room is the reason you bought the place, whether it looks like itself yet, because a garden in February is a different argument for the house than the same garden in June.
Where the word comes from
It is older than the modern flat-share suggests. the Online Etymology Dictionary dates housewarming to the 1570s, defining it as a "celebration of the entry of a family into a new home", from house plus a verbal noun from warm. The occasion has outlasted four and a half centuries of housing, so a fortnight either way is unlikely to be the thing that breaks it.
This opens the housewarming. Next to it, housewarming party ideas covers the evening itself, housewarming etiquette covers what guests owe you and you owe them, and how much to spend answers the question your guests are quietly asking each other. If somebody asks what to bring, housewarming gifts is the page to send them.
The 1570s date and the definition quoted from the Online Etymology Dictionary, read 3 September 2026.
