An adversarial pass found the rules throwing away the feast rank that
describe() computes, in exactly the seasons where it decides the answer.
- A saint of vigil or polyeleos rank now lifts a weekday of a fast, to wine
and oil inside the Great Fast and as far as fish in the three lesser
ones. This is why the printed calendars mark so many Wednesdays in the
Nativity Fast; 74 days across 2020-2030 were being reported stricter than
any published calendar keeps them, St Nicholas and the Forty Martyrs of
Sebaste among them.
- The Annunciation was tested after Great Friday and Great Saturday, so on
the years it lands there it vanished into them entirely -- the Great Feast
of the Incarnation demoted to a bullet, reported as a total fast, and its
rank overwritten with the lesser movable one the rules then read. It is
now tested first and lifts those days to wine and oil. Five such years
this century on the Gregorian paschalion, seven on the Julian.
- Lazarus Saturday and Palm Sunday belonged to no season at all, sitting
between the Forty Days and Great Week. Any rule keying on the season fell
through, so Byzantine Catholic jurisdictions reported a meat glyph and
'no fast' on Palm Sunday.
- The eves of the Nativity and Theophany are relaxed to wine and oil when
they fall on a weekend, which ruthenian.py already implemented and this
module did not.
Also: iCalendar folded on characters where RFC 5545 counts octets, so an
emoji put lines up to 80 octets over a 75-octet limit; a malformed --date
printed a traceback; the overlaid menologion was rebuilt for every single day
asked about; the Nativity of the Forerunner was ranked below its class.
Fourteen new tests, each one able to fail. The old sweep asserted only
all(d.fast), and 'none' is a truthy string.

# typikon
|
|
|
|
The Orthodox liturgical day — feasts, seasons and the fast — computed rather
|
|
than fetched.
|
|
|
|
Everything derives from the paschalion and the fixed calendar, so it needs no
|
|
network, cannot go stale, and answers for any year you ask about. No API key,
|
|
no service that might be gone next year, no cache to invalidate.
|
|
|
|
|
|
|
|
```console
|
|
$ typikon
|
|
Wednesday 18 March 2026 — 5 March in the church calendar
|
|
Russian Orthodox Church Outside Russia · the Typikon
|
|
|
|
🥬 The Holy Martyr Conon
|
|
|
|
xerophagy — no oil or wine
|
|

|
|

|
|
```
|
|
|
|
## Install
|
|
|
|
```console
|
|
$ pipx install git+https://git.pumpin.online/funkpower/typikon
|
|
```
|
|
|
|
Or run it straight out of a checkout — it has no dependencies and needs only
|
|
Python 3.9.
|
|
|
|
```console
|
|
$ git clone https://git.pumpin.online/funkpower/typikon
|
|
$ cd typikon && python -m typikon.cli
|
|
```
|
|
|
|
## Which calendar?
|
|
|
|
Three things get conflated constantly, and keeping them apart is most of what
|
|
this library is for:
|
|
|
|
| | |
|
|
|---|---|
|
|
| **Paschalion** | which table gives Pascha — Julian or Gregorian |
|
|
| **Menologion** | which calendar the fixed feasts are read on |
|
|
| **Rule** | which fasting discipline is kept |
|
|
|
|
Almost every Orthodox Church keeps the **Julian Paschalion**. What divides them
|
|
is the menologion. The old-calendar churches read the fixed feasts on the
|
|
Julian calendar too; the new-calendar churches read them on the Revised Julian,
|
|
which agrees with the Gregorian for every date until 2800. So a new-calendar
|
|
church keeps the Nativity with the West and Pascha with the East — not a
|
|
compromise but exactly what the 1923 congress decided.
|
|
|
|
Pick a reckoning without naming a church:
|
|
|
|
```console
|
|
$ typikon --calendar old # Julian throughout
|
|
$ typikon --calendar new # Revised Julian fixed feasts, Julian Pascha
|
|
$ typikon --calendar western # Gregorian throughout
|
|
```
|
|
|
|
Or name one, which also picks up its fasting rule and any local saints:
|
|
|
|
```console
|
|
$ typikon --jurisdiction rocor
|
|
$ typikon --jurisdiction antiochian --days 7
|
|
$ typikon --list # every accepted value
|
|
```
|
|
|
|
The first run writes your choice to `~/.config/typikon/config.toml` and stops
|
|
asking. Change it with `--set-default`, override it for one run with the flag,
|
|
or set `TYPIKON_JURISDICTION`.
|
|
|
|
Twenty-three jurisdictions ship: the old-calendar churches (Moscow, ROCOR,
|
|
Serbia, Georgia, Jerusalem, the Holy Mountain, Poland, Macedonia), the
|
|
new-calendar ones (Constantinople, Greece, GOARCH, Antioch, the OCA, Romania,
|
|
Bulgaria, Cyprus, Albania, Ukraine), the Finnish Orthodox Church — alone among
|
|
the Orthodox in keeping the Gregorian Paschalion — and, as an add-on, four
|
|
Byzantine Catholic churches.
|
|
|
|
## The fast
|
|
|
|
Six levels, ordered from strictest to laxest. They are the Typikon's own
|
|
distinctions, not a simplification of them:
|
|
|
|
| | |
|
|
|---|---|
|
|
| `strict` | no food until evening |
|
|
| `xerophagy` | no oil, no wine; no meat, fish, eggs or dairy |
|
|
| `wine_oil` | wine and oil permitted |
|
|
| `fish` | fish, wine and oil permitted |
|
|
| `dairy` | dairy, eggs and fish permitted; no meat |
|
|
| `none` | no fast |
|
|
|
|
A calendar that reports xerophagy and wine-and-oil both as "fasting" has thrown
|
|
away the information its reader wanted.
|
|
|
|
**Level and obligation are separate questions.** The Orthodox Church legislates
|
|
fasting as tradition rather than as precept, so every Orthodox day here reports
|
|
as customary. The Eastern Catholic churches do have law about it, and it
|
|
requires very much less than the Typikon describes — so those jurisdictions
|
|
report both the level at which the day is kept and the minimum that actually
|
|
binds. A calendar saying "obligatory" where nothing obliges is worse than no
|
|
calendar; one reporting only the binding minimum makes the obligatory days look
|
|
laxer than the voluntary ones beside them.
|
|
|
|
Where usages differ — Great Thursday, the Exaltation, Lazarus Saturday — this
|
|
follows the common published rule and names it in the day's reason so you can
|
|
disagree with it. Monastic practice, and the Holy Mountain in particular, is
|
|
stricter than all of it. A calendar cannot settle that; your bishop and your
|
|
spiritual father can.
|
|
|
|
## Output
|
|
|
|
```console
|
|
$ typikon --json --days 7 # for a bar, a widget, a script
|
|
$ typikon --ics --days 365 > orthodox.ics
|
|
$ typikon --year 2027 # a year's key dates, to check against yours
|
|
```
|
|
|
|
The JSON shape is flat and stable. Front ends are the thing most likely to be
|
|
written by someone else, and a schema that shifts underneath them is a bad
|
|
neighbour.
|
|
|
|
## As a library
|
|
|
|
```python
|
|
import typikon
|
|
|
|
d = typikon.today("rocor")
|
|
d.church_date # '5 September'
|
|
d.fast # 'xerophagy'
|
|
d.title # 'The Holy Prophet Zachariah, father of the Forerunner'
|
|
d.is_obligatory # False
|
|
|
|
typikon.julian_pascha(2027) # datetime.date(2027, 5, 2)
|
|
typikon.gregorian_pascha(2027) # datetime.date(2027, 3, 28)
|
|
|
|
for day in typikon.week(date, 7, "antiochian"):
|
|
...
|
|
```
|
|
|
|
## The menologion
|
|
|
|
The fixed calendar ships as data and is indexed by **ecclesiastical** date, so
|
|
one file serves every jurisdiction. An old-calendar church and a new-calendar
|
|
church both keep the Nativity on 25 December; they disagree about which morning
|
|
that is, and that disagreement lives in the calendar conversion, not in the
|
|
data.
|
|
|
|
`typikon/data/menologion.json` covers all 366 days with the principal
|
|
commemorations of the common Byzantine tradition, ranked so the fasting rules
|
|
know when a feast lifts a Wednesday. It was composed for this project and is
|
|
under the same licence as the code. It is a working set, not a complete
|
|
Synaxarion; additions are welcome.
|
|
|
|
Some churches also keep their own saints, and those lists are usually published
|
|
by a body that holds the copyright in the wording. Those are **not** shipped.
|
|
Fetch one onto your own machine instead:
|
|
|
|
```console
|
|
$ typikon --list-menaia
|
|
$ typikon --update-menaion ruthenian
|
|
```
|
|
|
|
It lands beside the packaged menologion and is overlaid automatically.
|
|
|
|
## Accuracy
|
|
|
|
`typikon` is pinned by 60 tests against published calendars — the paschalion
|
|
for six years by both reckonings, the Julian drift across the 2100 boundary,
|
|
the fast on every day that is not open to interpretation, and a full year in
|
|
every jurisdiction.
|
|
|
|
It is a calendar, not an authority. If it disagrees with the one your parish
|
|
prints, your parish is right. Please open an issue.
|
|
|
|
## Front ends
|
|
|
|
[`horologion`](https://git.pumpin.online/funkpower/horologion) — desktop
|
|
widgets for Hyprland (Quickshell), waybar and eww, all reading the JSON above.
|
|
|
|
|
|
|
|
## Licence
|
|
|
|
GPL-2.0-only — see [LICENSE](LICENSE). The menologion is under it too;
|
|
`typikon/data/LICENSE` says so and notes what the fetched sets are not.
