You can create DataFrames specifying holidays for particular countries and specify your own special dates to include them as features for forecasting.

import pandas as pd
from nixtla import NixtlaClient
from nixtla.date_features import CountryHolidays
from nixtla.date_features import SpecialDates
nixtla_client = NixtlaClient(
    # defaults to os.environ.get("NIXTLA_API_KEY")
    api_key = 'my_api_key_provided_by_nixtla'
)

👍 Use an Azure AI endpoint

To use an Azure AI endpoint, remember to set also the base_url argument:

nixtla_client = NixtlaClient(base_url="you azure ai endpoint", api_key="your api_key")

# Get country holidays for the US
c_holidays = CountryHolidays(countries=['US'])
periods = 365 * 1
dates = pd.date_range(end='2023-09-01', periods=periods)
holidays_df = c_holidays(dates)

# Specify your own special dates
special_dates = SpecialDates(
    special_dates={
        'Important Dates': ['2021-02-26', '2020-02-26'],
        'Very Important Dates': ['2021-01-26', '2020-01-26', '2019-01-26']
    }
)
periods = 365 * 1
dates = pd.date_range(end='2023-09-01', periods=periods)
special_dates_df = special_dates(dates)
