الفصول الأربعة is a unique calendar app that uses stars to determine the changing seasons. It was originally used on the Arabian Peninsula to track the four seasons and bird migration patterns throughout the year. This app stands out by notifying you when each season begins and provides detailed information about weather conditions, rainfall, agricultural seasons, and bird migration.

One of the app's notable features is its ability to send you notifications when a star appears, signaling the start of a new season. It also provides extensive details about the weather conditions during each season, allowing you to plan your activities accordingly. Additionally, it offers insights into agricultural seasons and bird migration patterns.

Please note that the app uses both the common calendar and the astronomical calendar developed by Khalid Al-Zuaq to calculate dates. You have the option to choose which calendar to use in the app's settings.

Please be sure to access the app's settings and select the appropriate calendar to start date calculations and receive notifications.

We kindly ask you to rate the app. Thank you.
