Devotions
A devotion has no last day. A novena ends on the ninth; the Angelus is still there tomorrow, and the month after that. Some of these run three times a day, some on one Friday a month for nine months.
Two of these are counted in months, not days, and the sequence can break. That is intrinsic to the devotions themselves and not a mechanic this site added — there are no notifications, no badges and no streak language anywhere, and when a sequence breaks the page says so plainly and without pressure.
