Why are griha pravesh and other auspicious ceremonies not performed at night?
Because work begun with the sun's energy goes well, and after sunset creation is considered asleep. So griha arambh, griha pravesh, factory openings and other mangalik events are held in daytime.

Are women given less importance when the house is read from the man's chart?
No, they are given full importance. The house is bought with the man's money, but its comforts are for the women. At griha pravesh the kalash chakra also checks the woman's rashi for the 4th, 8th and 12th positions, and women enter the house first.
Can a Vastu Devta already be active without any remedy?
Yes. Sometimes the devtas are active on their own because of one's punya and good karma of past lives; they are like old friends who wake up again when one comes to live on that land. They also become active when one moves in with the permission of the people already living there. The activation tests show whether they are active.
Do the swastiks for nazar and other uses need to be made at a particular time?
Select a muhurta if possible. Otherwise make swastiks for shanti and paushtik (peaceful, nourishing) work in the Chandra swar and for ugra (forceful) work in the Surya swar. Any remedy done in the wrong swar gives no result.
Does the time of offering matter when worshipping the devtas?
In a full vastu poojan all 45 devtas are worshipped and offered together. When one particular devta has to be activated, offer its bhog samagri or do its jaap in its own time slot for the maximum result. An offering at another time is not useless, but just as food eaten at the fixed time of hunger satisfies more, the result differs.
How long is each Vastu Devta's time period, and when are Shikhi and Parjanya active?
Each outer devta has a sadhana period of 45 minutes, so the 32 outer devtas complete the 24 hours (32 x 45 minutes) and come back to the same point. Shikhi's period runs up to 3:00 am and Parjanya's from 3:00 to 3:45 am. Havan and offerings made in a devta's own period wake and activate it quickly.
If many things are already kept at a devta's place, does that count as an offering?
No, goods lying there are not arpan or samarpan. A guest never picks sweets off the dining table himself; they are served on his plate and he is invited to start. In the same way, serve the devta its bhog in a leaf dona or on a paan leaf, which the devtas love, and request it to accept the offering and increase the energy of the place. If the pooja was not done during construction, offer it at griha pravesh: any dish made in desi cow ghee, such as gujiya.
