🎌 Yasumi - Blazing Fast Japanese Holidays for Python

Yasumi is a high-performance Python library for determining Japanese holidays, built with Rust and powered by Maturin. Yasumi offers the same functionality as the popular jpholiday library, but with 65x faster performance thanks to Rust's speed and efficiency.

If you're working with Japanese holidays in Python and need a significant boost in performance, Yasumi is your best choice!

🚀 Features

• 🌸 65x faster than jpholiday for holiday calculations.
• 🎏 Determine if a date is a Japanese holiday.
• 📅 Retrieve the name of the holiday on a specific date.
• 📆 Fetch holiday lists for any given year or range of dates.

🔧 Installation

You can easily install Yasumi via pip:

pip install yasumi

📖 Usage

Here’s how you can use Yasumi in your Python projects:

import yasumi
import datetime

# Check if a specific date is a holiday
date = datetime.date(2024, 1, 1) # or datetime.datetime is also available.
if yasumi.is_holiday(date):
    print(f"{date} is a holiday: {yasumi.holiday_name(date)}")
else:
    print(f"{date} is not a holiday.")

# Get all holidays for a given year
holidays = yasumi.year_holidays(2024)
for date, name in holidays:
    print(f"Holiday on {date}: {name}")

Available Functions

• is_holiday_name(date: datetime | date) -> str | None Check if the given date is a holiday and get its name, if available.
• holiday_name(date: datetime | date) -> str | None Get the name of the holiday on the given date, if it’s a holiday.
• is_holiday(date: datetime | date) -> bool Check if the given date is a holiday.
• is_no_workday(date: datetime | date) -> bool Determine if the given date is a non-working day (including holidays).
• month_holidays(year: int, month: int) -> list[tuple[date, str]] Get a list of holidays for a specific month in a given year.
• year_holidays(year: int) -> list[tuple[date, str]] Get a list of all holidays in a given year.
• holidays(start_date: datetime | date, end_date: datetime | date) -> list[tuple[date, str]] Get a list of holidays between the specified start and end dates.
• between(start_date: datetime | date, end_date: datetime | date) -> list[tuple[date, str]] Retrieve holidays that fall between the specified dates.

💡 Why Yasumi?

Yasumi is built with Rust, making it 65x faster than the Python-based jpholiday. This makes it perfect for applications where performance is critical, such as web services, data processing, and large-scale holiday calculations. With Yasumi, you get the speed of Rust with the ease of Python.
