advdate and datetime2 with day of week

Question

I'd like to increment the date in the format

[Day of week] [Day] [Month] [Year]

by one each step, but I can't get the day of the week to increment. I've been looking at this answer but I can't get dow to advance properly.

\documentclass{article}
\usepackage[british]{babel}
\usepackage[useregional,showdow]{datetime2}
\usepackage{advdate}
\usepackage{etoolbox}
\makeatletter
\appto\FixDate{%
  \edef@dtm@currentyear{\the\year}%
  \edef@dtm@currentmonth{\the\month}%
  \edef@dtm@currentday{\the\day}%
%  \edef@dtm@currentdow{\the\dow}%??
}
\makeatother
\begin{document}
\today
\AdvanceDate[1]
\today
\AdvanceDate[1]
\today
\AdvanceDate[1]
\today
\AdvanceDate[1]
\today
\end{document}

Answer 1

Here's an alternative approach using only datetime2:

\documentclass{article}
\usepackage[british]{babel}
\usepackage[useregional,showdow]{datetime2}
\NewDocumentCommand{\TODAY}{}{%
  \DTMifsaveddate{now}{}{\DTMsavenow{now}}% If "now" date doesn't exist, set it
  \DTMusedate{now}% Print date
}
% Partly taken from https://tex.stackexchange.com/a/318012/5764
\newcount\daycount
\NewDocumentCommand{\AdvanceTODAY}{ O{1} }{%
  \DTMsaveddateoffsettojulianday{now}{#1}\daycount% Identify Julian days
  \DTMsavejulianday{now}{\number\daycount}% Set new date
}
\begin{document}
\TODAY
\AdvanceTODAY% Defaults to advance 1 day
\TODAY
\AdvanceTODAY[1]
\TODAY
\AdvanceTODAY[2]
\TODAY
\end{document}
