We always decorate the Christmas tree on the morning of Christmas Eve.
Fixed preposition
When talking about events on this day, the preposition 'an' is almost always used. The correct form is 'an Heiligabend' (on Christmas Eve).
EXAMPLE

On Christmas Eve, many families go to church.

Heiligabend vs Weihnachten
Christmas
'Weihnachten' and 'der Heiligabend' are closely connected, but they are not the same. 'Weihnachten' means the whole holiday and often also several holidays at the end of December. 'Heiligabend' is only the evening of December 24, that is, the evening before Christmas Day. Many families celebrate especially on Heiligabend, so it is easy to confuse the words. If you mean exactly the evening of December 24, 'Heiligabend' is correct. If you are talking about the holiday in general, 'Weihnachten' is more natural.
Heiligabend
Am Heiligabend essen wir mit der ganzen Familie zusammen.
On Christmas Eve, we eat together with the whole family.
Weihnachten
An Weihnachten bleibt unser Geschäft drei Tage geschlossen.
At Christmas, our store stays closed for three days.
