I would like to be able to design some calendars.

While this doesn’t answer your question, did you try Willi’s calendar modules, as outlined in https://articles.contextgarden.net/journal/2022.html ? I guess the code also contains date calculations. Hi Hraban,

it doesn’t fit my needs (which are way different from his pocket diary). Having a command that increases or days (according to the calendar) avoids me having to implement the whole logic. Besides, I think \normalday could be way more useful if it could increment the whole date, not only the day number. I must admit that I barely understand how \normalday behaves like any other counter. Pablo

does this help?

I’m afraid not, because I wonder how to typeset a whole year with that os.date() and os.time() functions. I mean, a huge xtable that contains 12 months, with a variable number of weeks and days each, placing each day number in weeks from Monday to Sunday. I cannot even get a header with the correct year number (although I know how to invoke that, I get 2028 instead of 2024 [probably because of for-loops]). It seems that it is too complex for me (and I have already invested two afternoons in this). For some reason, not meant to be in my case, Pablo

Many thanks for the info, Wolfgang. This is something I need to keep in mind when I get weird results in loops. Many thanks for your help, Pablo

Many thanks for your three suggestions, vm. They would be a way to start doing it, but fortunately there is a proper calendar solution. Many thanks for your help, Pablo

Many thanks for your reply, Wolfgang. I‘m afraid that approach is too complex for me to implement a full calendar of previous, current and next year. I have tried that, but only the required xtable seems too complicated to me (using xtables). Pablo

tikz has various macros to typeset calendars: [...] Also see https://tikz.dev/library-calender and https://texample.net/ tikz/examples/feature/calendar-library/ (which, in principle, can be translated to ConTeXt rather easily).

Hi Aditya, many thanks for the reference: this solves all my needs (see below). It would be great (as per https://texample.net/tikz/examples/birthday-calendar/) to have automatic Easter calculation. I guess Lua code would be easier to write, but I cannot get how each Easter Sunday may be computed.

Hi Pablo, you didn’t follow my suggested links.

Sorry, Hraban, I followed the only link I got in my message. What I completetely overlooked was that there were two more articles by Willi about PocketDiary. I thought the first article was the module presentation for the new version. I had mistakenly thought that that first article was all it was about that. Apologies for my hurried reading (also to Willi), Pablo

Here you go: a = math.fmod(year,19) b = math.floor(year / 100) c = math.fmod(year,100) d = math.floor(b / 4) e = math.fmod(b,4) f = math.floor((b + 8) / 25) g = math.floor((b - f + 1) / 3) h = math.fmod((19 * a + b - d - g + 15),30) i = math.floor(c / 4) k = math.fmod(c,4) L = math.fmod((32 + 2 * e + 2 * i - h - k),7) m = math.floor((a + 11 * h + 22 * L) / 451) eastersundaymonth = math.floor((h + L - 7 * m + 114) / 31) eastersunday = math.fmod((h + L - 7 * m + 114),31) + 1 Thomas
