The **Liberalia Triday Calendar**is a proposal for Calendar Reform
by Peter Meyer. It combines a solar calendar with a lunar calendar which have *tridays* (periods of 3 days) in common.

Both the solar and lunar calendars start year 0 on 17 March 1904.

The three days of the triday are named

- Sophiesday
- Zoesday
- Norasday

So 17 March 1904 is a *Sophiesday*. Its Julian day number is 2,416,557 which is divisible by 3, so the *Sophiesdays* are those days whose Julian day number is divisible by 3.

The *lunar calendar* gives a very rough indication of the moon phase, not only because every month is a whole number of tridays (either 30 or 27 days), but also because the short 27-day months are not as evenly spaced as possible. However spacing the short months as evenly as possible would give rise to either a more complicated calendar or one in which the lunar years have a variable number of months.

## Dates Edit

- Solar date
- ±M*CYY
_{S}**-**Q**-**T**-**D - Lunar date: ±C*C
**-**YYY_{L}-Q**-**T**-**D

A cycle consists of 384 lunar years, each 354 or 357 days long.

Number | Name | Tridays | Days |
---|---|---|---|

1 | Kamaliel | 30 | 90 |

2 | Gabriel | 31 | 93 |

3 | Samlo | 30 | 90 |

4 | Abrasax | 30 (31) | 90 (93) |

Sum | 121 (122) | 363 (366) |

Abrasax only has 30 tridays if the solar year number plus one is divisible by 4 or by 198.

Number | Name | Tridays | Days |
---|---|---|---|

01 | Armedon | 10 | 30 |

02 | Nousanios | 10 | 30 |

03 | Harmozel | 10 | 30 |

04 | Phaionios | 10 | 30 |

05 | Ainios | 10 | 30 |

06 | Oraiel | 9 | 27 |

11 | Amethes | 10 | 30 |

12 | Eleleth | 9 (10) | 27 (30) |

Sum | 118 (119) | 354 (357) |

Eleleth has 9 tridays unless the lunar year number minus 2 is divisible by 8 and is not 2.
