The Sundays the calendar was not naming, and a calendar that keeps every day

Nine Sundays went unnamed in every jurisdiction. Three were missing from the
movable cycle outright: the Paralytic, the Samaritan Woman and the Blind Man,
so the fourth, fifth and sixth Sundays of Pascha reported only the saint of the
fixed date. Six more are reckoned from a fixed feast rather than from Pascha —
before and after the Exaltation, the Forefathers, before and after the
Nativity, before and after the Theophany — and were not modelled at all.

The three Pentecostarion Sundays rank with Thomas Sunday and the Myrrh-bearing
Women, so a vigil-rank saint still keeps the day and the Sunday is commemorated
on it. The six fixed-cycle ones never name a day: they are found in
ecclesiastical space, so the old calendar and the new get them on the right
morning, and they join the commemorations. Where a short window holds no Sunday
the Typikon says what to do and this follows it; where the books disagree, the
day goes unmarked rather than carrying an answer this calendar cannot defend.

`week` says where a day falls in the count from Pentecost, which is how the
books head the long ordinary stretch. It runs on across the new year and stops
at the Triodion, whose Sundays have names instead of numbers.

`--every-day` gives ics an event for every day, ferias included. The default
still thins the calendar, which is right for a subscription and wrong for a
reader who wants the saint of each morning; and the description now leads with
the commemorations rather than burying them under the church date.

Checked against 1.1.2 over every jurisdiction from 2015 to 2035: rank, feast
and title move on the three new Sundays and nowhere else. No fast, obligation,
binding or season changes on any day.

+## 1.2.0
+
+### Calendar
+
+- **The Pentecostarion keeps all of its Sundays.** The Sunday of the Paralytic,
+  the Sunday of the Samaritan Woman and the Sunday of the Blind Man were absent
+  from the movable cycle altogether, so the third, fourth and fifth Sundays
+  after Thomas Sunday reported only the saint of the fixed date. Every
+  jurisdiction was affected. In 2027 that is 18 and 25 April and 2 May by the
+  Gregorian paschalion, 23 and 30 May and 6 June by the Julian one. They rank
+  with Thomas Sunday and the Myrrh-bearing Women, so a fixed feast of vigil
+  rank still names the day and the Sunday is commemorated on it: 25 April 2027
+  stays St Mark and gains the Samaritan Woman.
+
+- **The Sundays reckoned from a fixed feast are kept.** Six more that the
+  calendar never named: the Sundays before and after the Exaltation, the Sunday
+  of the Holy Forefathers, the Sundays before and after the Nativity, and the
+  Sundays before and after the Theophany. They are found in ecclesiastical
+  space, so the old calendar and the new both get them on the right morning,
+  and they join the day's commemorations rather than displacing its saint.
+
+  Two years in the cycle leave a window without a Sunday in it, and the Typikon
+  says where those go: a Nativity on a Sunday puts the Sunday after it on 26
+  December, and a 1 January on a Sunday keeps the Sunday before the Theophany
+  with the Circumcision. The two remaining cases, the Theophany itself or the
+  Exaltation on a Sunday, go unmarked, because the books disagree about where
+  what belongs in them should land.
+
+### Added
+
+- `week`: where the day falls in the count from Pentecost, worded as the books
+  head it — `the 32nd Sunday after Pentecost`, or `the 32nd week after
+  Pentecost` on the days between. Null through the Triodion and the
+  Pentecostarion, whose Sundays carry names instead of numbers. The count runs
+  on across the new year from the Pentecost that opened it, and stops at the
+  next Sunday of the Publican and the Pharisee. It is in the JSON, a column in
+  `csv` and `tsv`, a line in the single-day view, and a getter on every
+  binding.
+
+- `--every-day`: one event per day in `--format ics`, ferias included. The
+  default still thins the calendar to the days carrying a feast or a fast,
+  which is right for a subscription and wrong for a reader who wants the saint
+  of each morning.
+
+### Changed
+
+- The iCalendar description leads with the day's commemorations, one to a line,
+  then the fast and its reason, then the season, the week and the church date.
+  They were last before, after the church date, and a client showing three
+  lines of a popover showed everything except what the day commemorates. The
+  summary now carries the rank's mark beside the fasting glyph, as the text
+  view has always done, and the fast is stated on every event rather than only
+  on the days that keep one.
+
+- `typikon::export::to_ics_with` and `Ics` are the way to reach the new option
+  from the library. `to_ics` is unchanged and still writes the thinned
+  calendar.
