📅 Streamlit Calendar Input

A custom Streamlit calendar widget that lets users select dates from a list of available options. Dates are shown month-by-month, with green marking available days and red marking unavailable ones.

🔧 Features

• 📆 Interactive calendar input widget for Streamlit
• ✅ Green: Available dates
• ❌ Red: Unavailable dates
• 🖱️ Click to select a date
• 🔄 Returns a Python datetime.date object

📦 Installation

pip install streamlit-calendar-input

🚀 Usage

import streamlit as st
from streamlit_calendar_input import calendar_input
import datetime

# Define available dates (e.g. from your backend, bookings, etc.)
available_dates = [
    datetime.date(2025, 6, 20),
    datetime.date(2025, 6, 25),
    datetime.date(2025, 7, 2),
]

# Call the calendar input
selected_date = calendar_input(available_dates)

# Display the selected date
if selected_date:
    st.success(f"You selected: {selected_date}")

🧠 How it Works

• The widget renders a calendar month by month.

• Each day is color-coded:

  • ✅ Green: Clickable, available in available_dates
  • ❌ Red: Not clickable, unavailable

• When a user clicks a green date, the widget returns the corresponding datetime.date object.

📌 Requirements

• Python 3.7+
• Streamlit 1.0+
