السَّنَةُ الكَبِيسَةُ, (S, K,) and عَامُ الكَبِيسِ, (L, Az, in TA, voce سُبَاطٌ, q. v.,) [The intercalary year; or leap-year; both in the Syrian, or Julian, reckoning, and in the Coptic;] the year from which, (مِنْهَا,) according to the S and K, but properly, for which, (لَهَا,) as in the work entitled القَوْلُ المَأْنُوسُ, a day is stolen (يُسْتَرَقُ) [and intercalated]; which is [once] in every four years; as in the S and K; for the said day is an addition thereto; (MF, TA;) the year in which the Syrians following the Greeks, add a day to the month
سُبَاط, [which corresponds to February, O. S.,] making it twentynine days instead of twenty-eight, which they do once in four years; (L;) [and that in which the Copts intercalate, at the end, six epagomenæ instead of five, which, in like manner, they do once in every four years.]
