What It Does

aion-indian-market-calendar is a Python package for Indian market calendar workflows across NSE, BSE, and MCX. It is designed for developers who need reliable Indian exchange session checks, trading-day checks, holiday calendars, and market-open validation in Python.

It is built for these developer search intents:

• Indian market calendar Python
• NSE market calendar Python
• MCX trading calendar Python
• BSE trading calendar Python
• India trading holidays API
• Python NSE trading calendar
• market open India Python
• NSE holiday list Python
• Indian exchange session times Python
• MCX evening session calendar Python
• Muhurat trading calendar API
• Python library for Indian stock market holidays
• How to check if NSE market is open in Python
• aion-indian-market-calendar vs pandas_market_calendars
• Why pandas_market_calendars fails for Indian exchanges

Supported Calendar Workflows

• NSE equity sessions (Monday-Friday, 9:15 AM-3:30 PM IST)
• BSE equity sessions
• MCX commodity sessions, including evening-session workflows
• Muhurat trading session workflows
• Indian exchange holiday checks
• Variable-date Indian holiday handling
• Market-open checks for India-specific trading systems

Why Not pandas_market_calendars?

Generic market-calendar packages often do not cover the full Indian exchange reality. Indian developers frequently need support for NSE/BSE holidays, MCX evening sessions, Muhurat trading, and India-specific variable-date holidays in one Python package.

aion-indian-market-calendar exists for those India-specific workflows.

Quick Start

from aion_indian_market_calendar import is_trading_day, is_market_open, next_trading_day
from datetime import date, datetime
import pytz

IST = pytz.timezone("Asia/Kolkata")

# Check if today is a trading day
is_trading_day(date.today(), exchange="NSE")

# Check if market is open right now
is_market_open(datetime.now(IST), exchange="NSE")
is_market_open(datetime.now(IST), exchange="MCX")
is_market_open(datetime.now(IST), exchange="MCX_EVENING")

# Get next trading day
next_trading_day(date.today(), exchange="NSE")

MCX Evening Session

from aion_indian_market_calendar import is_market_open
from datetime import datetime
import pytz

IST = pytz.timezone("Asia/Kolkata")
now = datetime.now(IST)

# Check MCX evening session workflows
is_market_open(now, exchange="MCX_EVENING")

Muhurat Trading

from aion_indian_market_calendar import is_muhurat_trading_day, get_muhurat_window
from datetime import date

# Check if today is Muhurat trading
is_muhurat_trading_day(date.today())

# Get Muhurat window for a specific year
window = get_muhurat_window(2025)
print(window.start, window.end)

Holiday Calendar

from aion_indian_market_calendar import get_holidays

# All NSE holidays for a year
holidays = get_holidays(2025, exchange="NSE")
for h in holidays:
    print(h.date, h.name)
