Direct detection experiments searching for the scattering of dark matter particles off nuclei expect an annual modulation in their event rate. In this presentation, I will review the theoretical predictions and the experimental status of the search for annual modulations, with a focus on ongoing and planned experiments using NaI detectors. In particular, I will discuss the interpretation of the DAMA signal and related model-building efforts.

The paper, contribution to the Proceedings of the IDM 2022 conference, reviews about the annual modulation of the dark matter signals in NaI(Tl), both in terms of experimental and model-building efforts. The paper can be published, once the small remarks in the following will be fulfilled.
- page 1 it is written: “… is predicted to switch sign at very low recoil energies (so-called anti-modulation)…”. Actually, once considering the energy resolution of the detectors such a “anti-mod” can be smeared out.
- page 1, the footnote: The author cites the paper ; however, the arguments of  have already been confuted by DAMA in ref:
1) Prog. Part. Nucl. Phys. 114 (2020) 103810 and
2) arXiv:2209.00882 (your ref. )
For an unbiased view, these should be cited as well.
- page 2: “… the DAMA collaboration has been observing an annual modulation in their nuclear recoil data…”. Actually, ... in the experimental single-hit data. No selection between electromagnetic and recoil data can be done at low energy.
- page 2: it is cited ref  for DAMA, however more updated ref is Nucl. Phys. At. Energy 22 (2021) 329 and your ref. . The significance is slightly larger.
