If you were born and raised in the UK, chances are nobody ever sat you down to explain your birth chart the way it might happen in India. Here is the short version.
Rashi (moon sign)
Your rashi is the zodiac sign the Moon was in at your exact time and place of birth. It is the single most-used piece of information in Indian astrology, referenced far more often than the sun sign familiar from Western horoscopes.
Nakshatra
Your nakshatra is a finer-grained placement, one of 27 lunar mansions the Moon passes through. It is used for naming traditions, matching compatibility and the dasha (planetary period) system.
Lagna (ascendant)
Your lagna is the zodiac sign rising on the eastern horizon at your exact birth moment. Unlike rashi and nakshatra, lagna changes roughly every two hours, so it needs a precise birth time to compute correctly.
Getting a UK birth chart right
Since these are all computed from your literal time and place of birth, a birth in Birmingham or Leicester is calculated with exactly the same precision as a birth in Mumbai, using the correct UK time zone (including whether British Summer Time applied) and coordinates.
