#PART 1 : PREPARE NEEDED DATA
#-----------------------------------

# set birth location

# group all birth time data together
birth_time = Time("23:40 31/12/2010 +08:00", geolocation)


#PART 2 : SET CUSTOM AYANAMSA
# note : must be set before making calling calculator
#-----------------------------------

#PART 3 : MAKE CALCULATION
#-----------------------------------

# note : must be set before making calling calculator
#-----------------------------------
