If you have health insurance, your GP gives you a "направление"
(referral) to see a specialist under the public health fund; a patient fee may still apply; without one you usually pay. To book, say: "Може ли да си запиша час?"
(can I make an appointment?). In an emergency, call 112. This is general information — rules change, so check with НЗОК (the health fund) or your doctor.

School in Bulgaria
The school year usually starts on 15 September — "първият учебен ден"
(the first school day) is a celebration with flowers for the teacher.

Market day
Every town has its "пазар"
(market), and many places have a weekly market day, often at the weekend.
