For the format specifiers, see [`man strftime`](https://man7.org/linux/man-pages/man3/strftime.3.html). Be careful: If you change this, you might no longer find your existing diary entries, because the diary assumes to find the journal files under another file name. Hence, a change in FMT shows an empty diary, at first. Rename all files in the DIARY_DIR to migrate to a new FMT. |

If `glibc` is installed, the first day of the week is derived from the current locale setting (`$LANG`, see `man locale`). Without `glibc`, the first weekday defaults to 1 (Monday), unless specified otherwise with this option. |
