Change a date, step through a month, pick a year. Every value on the left is computed in your browser by the same calls shown on the right.

Date conversion

Ethiopian → Gregorian

Gregorian 2026/7/2

Gregorian → Ethiopian

Ethiopian 2018/10/25

example.js
import { toEC, toGC } from 'kenat';

// 1. Convert Gregorian to Ethiopian
const ecDate = toEC(2026, 7, 2);
// Returns: { year: 2018, month: 10, day: 25 }

// 2. Convert Ethiopian to Gregorian
const gcDate = toGC(2018, 10, 25);
// Returns: { year: 2026, month: 7, day: 2 }
npm install kenat

What the engine knows

kenat has no dependencies. It parses, converts, counts and formats Ethiopian dates the way the calendar itself does.

  • Date conversion

    Convert between Ethiopian and Gregorian dates in both directions, including Pagume and leap years.

    toEC() · toGC()

  • Calendar grids

    Generate a month as rows of days with weekday headers, Ge'ez numerals, Gregorian twins and holidays attached.

    new MonthGrid()

  • Date arithmetic

    Add or subtract days, months and years, compare dates and measure the distance between them on the Ethiopian calendar.

    addDays() · diffInDays()

  • Ge'ez numerals

    Write any number in Ge'ez script and read it back, so dates look the way Ethiopian readers expect.

    toGeez() · toArabic()

  • Bahire Hasab

    Compute the movable fasts and feasts of any year — Nineveh, Lent, Fasika — from the traditional reckoning.

    getBahireHasab(year)

  • Holiday system

    Fixed and movable holidays with tags such as PUBLIC and RELIGIOUS, in Amharic or English.

    getHolidaysForYear()

Calendar UI without the styling you'd have to undo.

kenat-ui is headless: React hooks for date pickers, month grids, clocks and converters that manage state and leave every pixel to you — Tailwind, CSS modules or your own design system.

  • useDatePicker()
  • useMonthGrid()
  • useEthiopianClock()
  • useDateConverter()
  • useTimeConverter()
kenat-ui docs
MonthView.jsx
import { useMonthGrid } from 'kenat-ui'

const { grid, controls } = useMonthGrid({
  weekdayLang: 'amharic',
  weekStart: 1,
})

// grid.headers, grid.days — render them
// with your own markup and styles.
controls.goNext()

One engine, six bindings

The same conversion rules and holiday tables, kept in parity across every language Kenat ships for.
