First of all, Holi is celebrated on the Phalguna Purnima day.
Here i'm referring to the book "Essence of Dharma Sindhu" which quotes from Scriptures like Matsya Purana and others while discussing Vastu Prakarana:
Vaishaakhey Phalgune Poushey Shraaaney Maargasirshakey, Grihaarambha
Prave shoustah stambhocchraayas chashasyatey||
Grihaarambha, Stambhoddhaarana and Griha Pravesha are best performed
in the months of Vaishakha, Phalguna, Pousha, Shraavana, and
Margasirsha. Jyeshtha, Kartika Maagha Months are also beneficient as
per Narada Vachana. A Parna Griha or a grass house could be
constructed without any month or time. But a house in which one likes
to reside himself or the Main House should not be constructed in
So,to start with, Phalguna month is one of the best months to do a Griha Pravesha in.
Hence,apparently,one can do Griha Pravesha on any of the days of Phalguna irrespective of whether that day comes before or after Holi.
But having said that, there are other factors as well ,like Tithi-Nakshtra-Yogas etc,that are also to be considered with due importance.
Vaastu Shanti has to be performed only in the day time. There is an
opinion that Griha Pravesha might be done in the nights also, in
which case, this Shanti function might as well be done at the same
Dina Maasaadi of Grihaarambha. The Shubha Kaala for Griha Pravesha
is stated to be in Maagha,Ashviyuja Jyeshtha Maasaas; Mridu-Dhruva
Nashatras are the most suitable, while Kshipra-Chara Nakshatras are o
f medium value. Teekshna-Ugra-Mishra Nakshatras are not good. If the
Karta’s Janma Lagna is not in the Eighth position,the Graha Pravesha
Lagna is commended.
I have posted the above passage only to emphasize the fact that a whole lot of rules and conditions are needed to be checked upon before planning a Griha Pravesha.And you should always consult a Pundit for that because all the rules are not known to us.
