The same verse: Tajika Nilakanthi 1.16
Here an easy way is told by the revered astrologer Nilakantha, crest jewel of all astrologers, our guru's elder brother. The same verse is in Tajika Nilakanthi 1.16, with our English meaning there.
Simple meaning: Same verse as Tajika Nilakanthi 1.16; see its meaning there.

Another way: years gone in three places, plus a quarter, halved, plus a half; add the birth weekday and time.

Other methods: many exist, but they are left out as not needed.
अथात्ररात्रिजन्मनीष्टकालयोगे विशेषउक्तस्ताजिकालंकारे ॥
Night birth: add the day length and the night time gone to the weekday that has passed.
