Somali calendar

The Somali calendar, (Somali: Soomaali tiro ammin)، (سومَلي تِرو امّين) which is a moon-and-sun-based system, was used by Somali herders and farmers to determine the seasons and predict the weather. The Somali lunar calendar is known as dayax-tiriska (دَيَح تِرِسكَه) and the sun-based calendar is called amin-tiris (اَمين تِرِس) or shin-tiris (شِن تِرِس).
