Muhurat for a housewarming (griha pravesh)
Griha pravesh is the ceremony of entering a new home. Families often choose its date by muhurat, using the nakshatra, weekday and tithi that the family's tradition prefers.
What it is
Common choices include nakshatras that are considered stable, weekdays that are considered favourable, and avoiding Rahu Kaal and similar periods. The lists differ, and the family's practitioner decides which to use.
How it is worked out or read
The muhurat finder on this site lists days that match nakshatra and weekday filters you choose at sunrise. It does not apply the full set of rules a family may use, so use it as a list of candidate days.
Where it appears on this site
The muhurat finder lists candidate days. The Rahu Kaal article explains one period to avoid.
Three kinds of entry
Traditional texts distinguish three kinds of house entry. Apoorva griha pravesh is the first entry into a newly built house. Sapoorva griha pravesh is re-entry into an existing house after a long absence, such as after travel or a period away. Dvandva griha pravesh is re-entry after renovation or after damage from fire, flood or other events. The rules for choosing a time are strictest for the first kind and more relaxed for the others.
Months and seasons
Many traditions prefer Uttarayana, the Sun's northward half of the year, for a first entry. Among lunar months, Magha, Phalguna, Vaishakha and Jyeshtha are widely favoured. The four months of chaturmas, roughly from Ashadha to Kartika, are commonly avoided, as is an adhik maas. Some traditions also avoid the period when the Sun is in Dhanu or Meena, often called kharmas. Regional practice varies, and the family's almanac usually lists the permitted dates.
Tithi, nakshatra and weekday
Favoured tithis in many lists are the second, third, fifth, seventh, tenth, eleventh and thirteenth of the bright fortnight; the Rikta tithis and Amavasya are avoided. Favoured nakshatras are usually the fixed and gentle ones: Rohini, Mrigashira, Chitra, Anuradha, Revati and the three Uttaras. Tuesday is widely avoided, and some traditions avoid Sunday and Saturday as well. The Lagna at the moment of entry is ideally a fixed sign with benefics in kendras and the eighth house free of malefics.
Using the tools
The muhurat finder on this site can list days in a chosen range whose sunrise nakshatra and weekday match the ones you tick. For a griha pravesh, tick the nakshatras above and exclude Tuesday, then check each candidate day's tithi, month and Rahu Kaal on the panchang page. Because the nakshatra can change during the day, note its end time and plan the entry while it still holds.
Keeping it practical
A new home often comes with fixed constraints: the handover date, a lease, school terms or a job. Where the ideal muhurat cannot be met, many families perform the puja and the ceremonial entry at a good time on an available day, sometimes moving only a symbolic item first, such as a pot of milk or a lamp, and moving the rest of their belongings later. The intention to begin well is what the custom expresses.
