זֶה־הַ֭יּוֹם עָשָׂ֣ה יְהוָ֑ה נָגִ֖ילָה וְנִשְׂמְחָ֣ה בֽוֹ׃
Ten to dzień sprawił Bóg, radujmy się i cieszmy nim.
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.
