The president approved the law on 11 October 2024, and it was officially published on 14 October 2024. https://www.gacetaoficial.gov.py/index/detalle_publicacion/89723 The text of the law says that it enters into force on the first Sunday in October 2024 (6 October 2024). But the constitution prohibits retroactive effect, and the civil code says that laws enter into force on the day after their publication or on the day that they specify, and it also says that they don't have retroactive effect. So I think that the time change on 6 October 2024 should still be considered as DST according to the previous law, and permanently UTC-3 from 15 October 2024 according to the new law. But in practice it doesn't matter. https://www.constituteproject.org/constitution/Paraguay_2011 https://www.oas.org/dil/esp/codigo_civil_paraguay.pdf
