Methodology and sources

Three kinds of date appear on this site, and every one is labelled.

Easter and Mardi Gras: computed, then checked

Easter is computed with the anonymous Gregorian algorithm (Meeus/Jones/Butcher); Mardi Gras is Easter minus 47 days. The build compares every year with independent published tables and refuses to publish if any date disagrees. Result of this build: 49 of 49 checks agree.

How often the usual patterns held

For every festival and krewe with a pattern rule, we projected the rule onto each year for which we have a real date (held or announced) and compared. 73 of 79 fell exactly on the projected start date. The misses are why pattern dates are never shown as dates.

Weather data

Monthly highs, lows, rainfall and dew point come from the TerraClimate 1991–2020 climatology (Abatzoglou et al. 2018, CC0), read over OPeNDAP for the grid cell containing Jackson Square. Dew point is derived from TerraClimate's vapour pressure; we do not publish relative humidity, which that method gets wrong.

Cross-check against NOAA NCEI 1991–2020 normals for New Orleans International Airport (MSY, station USW00012916, US public domain). The airport is about 18 km west of the French Quarter, inland and suburban, so small differences are expected; TerraClimate runs slightly warmer by day and cooler at night.
