זֶה־הַ֭יּוֹם עָשָׂ֣ה יְהוָ֑ה נָגִ֖ילָה וְנִשְׂמְחָ֣ה בֽוֹ׃
이 날은 여호와의 정하신 것이라 이 날에 우리가 즐거워하고 기뻐하리로다
Mishneh Torah, Scroll of Esther and Hanukkah
The whole day is fit for reading the Hallel. And one who reads the Hallel out of order has not fulfilled [the obligation. If] he read and paused and went back to read it — even if he paused long enough to finish all of it — he has fulfilled [his obligation. On] days that we complete the Hallel, one may interrupt between one section (paragraph) and [another]. But he may not interrupt in the middle of a section. However on days on which we read with skipping, he may interrupt even in the middle of a section.
