Server Side Usage

To convert date from A.D to B.S. and vice versa programatically you can make use of BikramSamvat python class provided by this module. Examples:

CODE EXAMPLE: Instantiate B.S. date

# Import date converter
from odoo.addons.nepali_date.convert_date import BikramSamvat

# Today's B.S. date
bs_date_today = BikramSamvat()

# To get A.D. date from B.S. date instance access `date` property
ad_date_from_bs_date = bs_date_today.date

CODE EXAMPLE: Convert from A.D. date to B.S. date

from datetime import date
import logging

# Import date converter
from odoo.addons.nepali_date.convert_date import BikramSamvat

# Convert from A.D. date
ad_date = date(1992, 5, 30) # instantiate A.D. date
ad2bs_date = BikramSamvat(ad_date) # convert from A.D. date to B.S. date

logging.info(ad2bs_date.format('MMMM dd, yyyy')) # print formatted B.S. date to stdout
# Outputs: Jestha 17, 2049

CODE EXAMPLE: Convert from B.S. date to A.D. date

from datetime import date
import logging

# Import date converter
from odoo.addons.nepali_date.convert_date import BikramSamvat

# Convert  from B.S. date
bs_date = BikramSamvat(2046, 12, 12)
bs2ad_date = bs_date.date # get B.S. to A.D conversion

logging.info(bs2ad_date.strftime('%B %d, %Y')) # print formatted A.D. date to stdout
# Outputs: March 25, 1990

logging.info(bs_date.format('MMMM dd, yyyy')) # print formatted B.S. date to stdout
# Outputs: Chaitra 12, 2046

CODE EXAMPLE: B.S. date manipulation

from datetime import date
from dateutil.relativedelta import relativedelta

import logging

# Import date converter
from odoo.addons.nepali_date.convert_date import BikramSamvat

# Instantiate B.S. date
bs_date = BikramSamvat(2077, 4, 28)

# Calculate next month based on B.S. date system
next_month_date_bs = bs_date + relativedelta(months=1)

# Calculate previous year based on B.S. date system
prev_year_date_bs = bs_date - relativedelta(years=1)

# Calculate next week
next_week_date_bs = bs_date + relativedelta(weeks=1)

# Complex calculation
calculated_date_bs = ((BikramSamvat() + relativedelta(years=2, months=6, weeks=2)) - relativedelta(days=1))
calculated_date_bs_to_ad = calculated_date_bs.date

# Supported relative properties
# years, months, weeks and days
