+====== Generally useful and important system stuff on unixoid systems ======
+===== Calendar =====
+e.g. on Debian the oldschool ''cal'' tool is not available at all. ''ncal'' is available via apt, but it behaves differently. Same as in cal, ncal starts weeks with sunday per default - with  ''-M'' you can can change this to mondays.
+<WRAP group>
+<WRAP column>
+But it still looks differently:
+<cli>
+ncal -M
+    February 2024
+Mo     5 12 19 26
+Tu     6 13 20 27
+We     7 14 21 28
+Th  1  8 15 22 29
+Fr  2  9 16 23
+Sa  3 10 17 24
+Su  4 11 18 25
+</cli>
+</WRAP>
+<WRAP column>
+This can be changed by adding the ''-b'' option:
+<cli>
+ncal -bM
+   February 2024
+Mo Tu We Th Fr Sa Su
+  2  3  4
+  6  7  8  9 10 11
+13 14 15 16 17 18
+20 21 22 23 24 25
+27 28 29
+</cli>
+</WRAP>
+</WRAP>
+<alert>The ''-b'' option also brings back the ability to print the a whole year, which is also not available without using this option.</alert>
