BTW, is there some description of your API on the WWW somewhere?
The code is freely available from http://pobox.com/~djb/libtai.html. I've started putting up API pages for the next release; in particular, http://pobox.com/~djb/libtai/caldate.html is done.
An alternative API _might_ provide a set of fields (again like tm in Markus' and Paul E's API) that could include day of week and week of month and then be willing to figure the MJD from whatever is provided.
Who cares? Remember that the point of libtai is to support real programs, not to build an API in the sky.
I would also hope that that any header file would define SUNDAY, MONDAY, TUESDAY etc. so I don't have to know the convention, even if there is an ISO standard.
Why would a program want to refer to specific weekdays, rather than having a table of all the weekdays?
I hope that is with or without consideration for local TZ.
What are you talking about? The Gregorian calendar does not depend on your local time zone.
I'm underwhelmed by the need when using your API to put together and take apart a MJD and all fields, once for each day just to walk back to a nearby weekday.
This need is a figment of your imagination. The reason I wrote ``there are faster ways to do this, of course'' was to forestall this pointless discussion. ---Dan
