repcal 1.1

The French Republican calendar and decimal time in Python

Repcal

A script that converts date and time to the systems used by the French Republic, the calendar from 1793 to 1805 and decimal time for about a year between 1794 and 1795. More information can be found on Wikipedia.

It uses the Romme method of calculating leap years, as in keeping the ones used by the French Republic and using the Gregorian rules for the years after the calendar was abolished.

Installation

$ pip install repcal

Usage

The current local time is used by default.

$ repcal
5:80:63, quartidi 24 Brumaire an CCXXIX

Or, for the full Republican experience, it can default to Paris Mean Time (6.49 decimal minutes ahead of GMT).

$ repcal --paris-mean
5:45:47, quartidi 24 Brumaire an CCXXIX

It also accepts date, time and format as arguments.

$ repcal '1969-07-20 20:17:40'
8:45:60, primidi 1 Thermidor an CLXXVII

$ repcal '1969-07-20'
primidi 1 Thermidor an CLXXVII

$ repcal '20:17:40'
8:45:60

$ repcal '1969-07-20' --format '{%d} {%B}'
1 Thermidor

As a Python package

from repcal import RepublicanDate, DecimalTime
from datetime import datetime

n = datetime.now()
rd = RepublicanDate.from_gregorian(n.date())
dt = DecimalTime.from_standard_time(n.time())

print(rd) # quartidi 24 Brumaire an CCXXIX
print(dt) # 5:79:47
