Where can I retrieve a complete history of macro economic data annoucements? I'd like to get the complete ( well at least the last 20 years) history of economic data announcement calendar firstly for US and secondly for G5 countries.
I have found many websites that propose the real time calendar so they yield the upcoming economic announcement dates but do not keep the previous announcement date (or at max the previous year)
For instance:
https://tradingeconomics.com/calendar
or https://www.newyorkfed.org/research/calendars/nationalecon_cal.html
or https://finance.yahoo.com/calendar/economic/
Having the figures of the economic indicators would be a plus.
Any clues guys?
Thanks
