Built a data set with Alteryx that calculates major US holidays, holiday weekends, various day of week/month columns, weekend flags, etc. US holidays were calculated on the fly using the current timing and the dates run from 1947 to 2050... I had a data input for Easter (Only calculated Gregorian Easter...). Some are anachronistic in that I calculated an MLK day in the 1950's, so feel free to improve some of those!! Thought this would be at least a fun thought starter for folks. I tried finding a good version online and was surprised to not be able to easily find anything that did this comprehensively and well.
Working on a Time Series flow, and I will definitely plug this in to help me set time to 'day in this period versus same day in last period' (i.e. calendar day and not calendar date) before generating plots and forecasts...
I also think it will be a cool lookup to leverage when trying to forecast, for example, the next Monday based on all the previous Monday's in the period even given Holiday effects.
Hi @justin_winter this is really a great and impressive workflow. I saved it for future needs! Currently I face however, another challenge regarding date matching. Maybe you - as an Day Time Ninja - wanna have a look at it?
