holidays.rest Python SDK

Official Python SDK for the holidays.rest API.

Requirements

• Python 3.10+
• httpx (only dependency)

Installation

pip install holidays-rest

Quick Start

from holidays_rest import HolidaysClient

with HolidaysClient(api_key="YOUR_API_KEY") as client:
    holidays = client.holidays(country="US", year=2024)
    for h in holidays:
        print(h.date, h.name.get("en"))

Get an API key at holidays.rest/dashboard.

API

HolidaysClient (sync)

from holidays_rest import HolidaysClient

client = HolidaysClient(
    api_key="YOUR_API_KEY",   # required
    timeout=15.0,             # optional, default 15s
)

Supports use as a context manager (with statement) to close the underlying connection pool on exit.

---

AsyncHolidaysClient (async)

from holidays_rest import AsyncHolidaysClient

async with AsyncHolidaysClient(api_key="YOUR_API_KEY") as client:
    holidays = await client.holidays(country="US", year=2024)

Both clients expose identical methods — only the async/await syntax differs.

Models

All responses are deserialized into dataclasses.

@dataclass
class Holiday:
    country_code: str          # e.g. "DE"
    country_name: str          # e.g. "Germany"
    date: str                  # "YYYY-MM-DD"
    name: dict[str, str]       # {"en": "New Year's Day", "de": "Neujahr", ...}
    is_national: bool
    is_religious: bool
    is_local: bool
    is_estimate: bool          # True when the date is algorithmically estimated
    day: DayInfo               # day-of-week, actual vs observed
    religion: str              # e.g. "Christianity", empty string if not applicable
    regions: list[str]         # subdivision codes, e.g. ["BW", "BY"]

@dataclass
class DayInfo:
    actual: str                # day the holiday falls on, e.g. "Thursday"
    observed: str              # day it is observed (may differ for weekend holidays)

@dataclass
class Country:
    name: str
    alpha2: str
    subdivisions: list[Subdivision]

@dataclass
class Subdivision:
    code: str
    name: str

@dataclass
class Language:
    code: str
    name: str

Error Handling

Non-2xx responses raise HolidaysApiError:

from holidays_rest import HolidaysClient, HolidaysApiError

with HolidaysClient(api_key="YOUR_API_KEY") as client:
    try:
        holidays = client.holidays(country="US", year=2024)
    except HolidaysApiError as e:
        print(e.status_code)  # HTTP status code
        print(str(e))         # Error message
        print(e.body)         # Raw response bytes

Status	Meaning
400	Bad request
401	Invalid API key
404	Not found
500	Server error
503	Service unavailable
