Note this here. Of what country are the planets of a panchanga (almanac)? And of what country is the person born? The true planets of people of every country cannot be made from an almanac made in one country. For with a change of country, corrections apply. They are deshantara (correction for distance east or west), bhujantara (time correction for the Sun's uneven motion), udayantara (rising-time correction), the chara (day-length difference) in palas (24-second units) and so on. So the Sun and all the planets are seen otherwise. So for the people of a country, make the true planets from that country's almanacs, which give true planets. Not from another country's.
Simple meaning: Use a local almanac: an almanac made for one country does not give true planets for people born in another.
अथ लग्नाद्द्वादशभावसाधनम् । उक्तं च जातकसुधानिधौ ॥
Why work out the houses: planets give each house's good and bad, so the houses must be found for birth, year and question charts.
ताजिकतिलकेपि ॥
Houses come first: for year, question, journey and birth charts, work out the houses before anything else.
भावानां नामान्युक्तानि ताजिकमुक्तावल्याम् ॥
Names of the 12 houses: body, wealth, brother, friend, son, enemy, wife, 8th, duty, work, gain, loss.
