Xilofat davlatida ish va vaqt tizimi hijriy taqvimdir. Hijriy yil 354 kundan iborat bo'lib, ulardan 3 kun muborak Ro'za hayit kunlariga, yettita kun esa Qurbon hayitiga ajratilgan. Shunday qilib, 344 kun quyidagi jadvalda ko'rsatilganidek, 4 o'quv choragi o'rtasida taqsimlanishi qoladi:

The system of work and time in the Khilafah State is the Hijri calendar. The Hijri year is composed of 354 days with 3 days set aside for the days of the blessed Eid Al-Fitr and seven days for Eid Al-Adha. Thus 344 days remain to be divided between the 4 school terms as shown in the following chart:

Birinchi maktab kursi har yili Muharram al-Harom oyining birinchi kunida boshlanadi va o‘sha davrda uchraydigan juma kunlari ham qo‘shilgan holda 83 kunni tashkil etadi; unga shu o‘quv choragining yakuniy imtihon davri ham kiradi. Shunga ko‘ra, kurs boshlanganidan 83 kun o‘tgach tugaydi. So‘ngra, oldingi chorak yakunida 3 kunlik ta’til berilgach, keyingi kurs boshlanadi.

The first school course commences on the first day of Muharram Al-Haram every year for a period of 83 days including the Fridays occurring in that period; it also includes the final examination period of that term. The course therefore ends after 83 days from its start. Then the next course commences after a holiday of 3 days at the end of the previous term.

To'rtinchi chorak alohida ahamiyatga ega, chunki unga Ramazon oyi, shuningdek Ro'za hayit va Qurbon hayit kunlari kiradi. Ba'zi talabalar yoki ustozlar hajni yoki umrani ado etish uchun yoki sayohat qilish maqsadida butun chorakni ta'til sifatida olishlari mumkin. Ba'zilar esa hajni muborak Qurbon hayit ta'tilida, ya'ni jami 7 kun davomida ado etishadi.

The fourth term is a distinguished one as it includes the month of Ramadhan as well as blessed days of the Eids of Al-Fitr and Al-Adha. Some students or teachers may take the whole term as a holiday to perform the obligation of Hajj, or Umrah or to travel. Some may also perform the obligation of Hajj in the holiday of the blessed Eid Al-Adha which totals 7 days.
