# Clock and Calendar Dataset
## Overview
This dataset comprises a **small** sample of two subsets: **Clock** and **Calendar**.
Each subset contains images paired with corresponding questions and answers, making it suitable for evaluating the reasoning capabilities of multimodal large language models (MLLMs) for calendar and analog clock interpretation.
## Dataset Structure
The dataset is organized into two main categories:
- **Clock Dataset**
- **Calendar Dataset**
Each entry in the dataset includes:
- **type**: Category of the clock/ year of calendar.
- **question**: A question related to the time or date displayed in the image.
- **answer**: The correct answer to the question.
- **image**: Image of clock or calendar.
## Clock Dataset
The Clock dataset contains various types of clock images with associated questions and answers about the time shown.
### Clock Data Categories:
- **Basic clock**: Standard analog clocks.
- **Black dial clock**: Clocks with a black dial background.
- **No second hand**: Clocks without a second hand.
- **Easy**: Clocks displaying simple hour-based times (e.g., 1-hour, 2-hour marks).
- **Roman**: Clocks using Roman numerals for hour representation.
- **Hand as arrows**: Clocks where the hands are represented as arrows.
## Calendar Dataset
The Calendar dataset contains images of yearly calendars with questions related to specific dates.
### Calendar Data Categories:
- **Popular days**: Questions related to Christmas and New Year's Day.
- **Less popular day**: Questions about the Ides of March (March 15th).
- **Random date**: Questions about a randomly selected date (November 21st).
- **Count-based days**: Questions about the 100th and 153rd day of the year.
