Add week day to calendar

Question

Is there a way to create a week count in this calendar? I am interested in including text to consider the number of the week, would this be possible using the used for loop?. I tried creating a new counter for the week and then update it as soon Monday is reached so that the week counter adds 1 but I could not make it work with this approach.

Any suggestions?

Answer 1

There is no built-in function for the weekdate number in the calendar module.

But we can add one!

This solution uses the ISO 8601. This means:

1. A new week starts on Monday.
2. The first week of the year has Jan 4th (= the year starts on Mon, Tue, Wed or Thu).
3. Week 53 exists in Common Years when they start/end on a Thu, leap years have week 53 when they either end or start on a Thu.
4. There's no week 0.

My solution stores away the calculation in a macro called \pgfcalendar@weeknumber@<year> so that it doesn't need to calculated at worst 366 times in a year. (Though, \pgfcalendar also doesn't just increment days/months/year/weekday and does a lot of calculations everytime.)

Some conditions are involved around the last and first days of the year since we either need to find out the weeknumber of the previous year or check for 3.

The code is part of my tikz-ext package. It provides the LaTeX package pgfcalendar-ext and the TikZ library ext.calendar-plus.

If you really want to count up, I suggest to use my solution at the first day of the year and when your counting reaches 53 (because sometimes 1 follows after 52).

---

Macro:

\pgfcalendarjulianyeartoweek{<julian count>}{<year>}{<week number count>}

The parameters are

1. a count with the Julian date (inside pgfcalendar this is \pgfcalendarcurrentjulian)
2. the year (yes, we could calculate that from 1. again but that's work, inside of pgfcalendar we can use \pgfcalendarcurrentyear)
3. a count that will the week number

Here's an example of how you could access this inside a simple \pgfcalendar.

Further down, I show the full usage of my libraries with the week numbers (including the appropriate styles and new shorthands).

Code

\documentclass{article}
\usepackage{pgfcalendar-ext}
\newcount\myCount
\begin{document}
\pgfcalendar{}{2022-01-01}{2022-12-31}{
  Julian day \the\pgfcalendarcurrentjulian\space is
  \pgfcalendarcurrentday.\,\pgfcalendarcurrentmonth.\,\pgfcalendarcurrentyear\space has week number
  \pgfcalendarjulianyeartoweek{\pgfcalendarcurrentjulian}{\pgfcalendarcurrentyear}{\myCount}%
  \the\myCount\par}
\end{document}

Output

Code

\usetikzlibrary{ext.calendar-plus}
