Check If The Date Is Open Date

from datetime import datetime

print(StockTools.check_is_open_date(datetime.strptime('2020/10/23', '%Y/%m/%d').date()))
# check if 2020/10/23 is open date, it will type error because it's not type of datetime.time
print(StockTools.check_is_open_date('2020/03/18'))

Converting Date Between Republic Era And Ad

from tw_stock_plugin import StockTools

# convert 109/10/10 to ad, it allow Y/m/d and Y-m-d format
print(StockTools.republic_era_to_ad(date_='109/10/10'))
# convert 2020/10/10 to republic era, it allow Y/m/d and Y-m-d format
print(StockTools.ad_to_republic_era(date_='2020/10/10'))

this tool is very useful when crawling tpex api.
