Valid reasons to miss a fast, whether make-up days must be consecutive, and the deadline to finish them.

Missing a day of fasting during Ramadan for a valid reason doesn't erase the obligation — it postpones it. This make-up fast is called Qada (قضاء), and while the basic rule is simple (one missed day equals one made-up day), the details around timing, order, and deadlines are where most people get confused, especially when several Ramadans' worth of missed days start to pile up.
Qada al-Sawm is the obligation to fast one day, at any later time outside Ramadan, to replace a day of Ramadan that was broken or missed for a legitimate Shari'a reason. It is a straightforward one-for-one replacement: unlike Kaffarah, there is no extra penalty attached to Qada itself, since the missed day was excused in the first place.
Islamic law recognizes several legitimate excuses for breaking or skipping a fast, all of which create a Qada obligation once the excuse ends:
Old age and permanent, non-recoverable illness are treated differently: instead of Qada, these cases move to Fidyah, since the person is not expected to ever be able to make up the fast.
No. Across the four Sunni schools of thought, the dominant view is that Qada days do not need to be fasted back-to-back. You can spread them across weeks or months, fasting whenever is practical for your health, work, and travel schedule, as long as every missed day is eventually replaced.
Most scholars hold that Qada should ideally be completed before the next Ramadan arrives, since a new Ramadan brings its own set of obligations. If circumstances mean you are still behind by the time the next Ramadan starts, most opinions still require completing the outstanding days afterward — but it's best to consult a qualified scholar if you are significantly behind, since some schools attach an additional Fidyah for unreasonable delay.
Qada cannot be fasted on the two days of Eid — Eid al-Fitr and Eid al-Adha — or on the three days of Tashreeq that follow Eid al-Adha, since fasting is prohibited for everyone on those five days regardless of the reason.
These three terms are often confused, but each covers a different situation. Qada is a like-for-like replacement for a day missed with a valid, typically temporary excuse. Fidyah applies instead of Qada when someone is permanently unable to fast, such as due to old age or a chronic illness — see Ihsabha's Fidyah Calculator Guide for how that's calculated. Kaffarah is a much heavier expiation owed only when a fast is broken deliberately, without any excuse at all — covered in Ihsabha's Kaffarah Calculator Guide.
Suppose someone missed 6 days of fasting across two Ramadans due to travel and short illnesses. Since consecutive fasting isn't required, they could plan to fast one day a week for six weeks, choosing days that don't clash with work or other commitments, and complete their Qada well before the next Ramadan begins.

Qada al-Sawm is the obligation to fast one day at any later time, outside Ramadan, to replace a Ramadan day you broke or missed for a valid Shari'a reason such as illness, travel, or menstruation.
No. The mainstream position across the four Sunni schools is that Qada days can be fasted on separate, non-consecutive days, in whatever order is practical, as long as they are all eventually completed.
Most scholars hold that Qada should ideally be finished before the next Ramadan begins. If you are significantly behind, it is best to consult a qualified scholar about your specific situation.
Whether a particular circumstance qualifies as a valid excuse, and how strictly the pre-next-Ramadan deadline is applied, can vary by school of thought and personal situation. This guide covers the widely-followed general rulings; for anything unusual — repeated delays, chronic health conditions, or a large backlog of missed days — confirm the details with a qualified local scholar.
