When the Beis HaMikdash stood, Yom Tovim were enjoyed through the shlomim sacrificial offerings. Without the Beis HaMikdash, the Rambam suggests in his Mishnah Torah some other ways to rejoice, Kloyes is one of them!
On these days, a person is obligated to be happy and in good spirits; he, his children, his wife, the members of his household, and all those who depend on him, as [Deuteronomy 16:14] states: “And you shall rejoice in your festivals.”
The “rejoicing” mentioned in the verse refers to sacrificing peace offerings, as will be explained in Hilchot Chaggigah. Nevertheless, included in [this charge to] rejoice is that he, his children, and the members of his household should rejoice, each one in a manner appropriate for him. What is implied? Children should be given roasted seeds, nuts, and sweets. For women, one should buy attractive clothes and jewelry according to one’s financial capacity. Men should eat meat and drink wine, for there is no happiness without partaking of meat,nor is there happiness without partaking of wine.
