Is there any up-to-date list of hours of work needed to buy a Big Mac? Is there any up-to-date list of hours of work needed to buy a Big Mac?

I have found only up to 2018.
I could not find any more recent Big Mac Index in terms of hours worked, and I dont think it is avaiable as wage statistics is usually reported with 1-2 year lag in many countries, but the Economist provides the Big Mac Index in USD, EUR, GBP and few other currencies up to January 2020  and it is being kept up to date with about 1 quarter lag. You can find the index here and raw data for all years here. 

Based on their index you can calculate how many hours (or in this case mostly minutes) it takes in some selected countries. For example you can find hourly wages by month in the US for 2020 at the U.S. Bureau of Labor Statistics. You will be able to do this for most rich developed countries but not for all countries around the world.
