import panchanga

# Convert date
jd = panchanga.modern_date_to_julian_day(2025, 3, 14)
ahargana = panchanga.julian_day_to_ahargana(jd)

# Get calendar information
kali_year = panchanga.ahargana_to_kali(ahargana)
saka_year = panchanga.kali_to_saka(kali_year)

# Calculate astronomical positions
tslong = panchanga.get_true_solar_longitude(ahargana)
tllong = panchanga.get_true_lunar_longitude(ahargana)

See the panchanga library documentation for more details.
