the third country in South America with the shortest day

Reduction of working hours to 40 hours per week It is already a reality in Mexicoafter his approval and publication in the Official Gazette of the Federation (DOF). Now, the country begins a period of progressive adaptation that will end in 2030 with a 40 hour work day weekly. This milestone places Mexico in an advantageous position with respect to the rest of the continent, being the third country in South America with the shortest working day. This change comes in a context in which the majority of Latin American countries still maintain a 48-hour work week, while only Ecuador and Chile have until now had a 40-hour regulation like the one Mexico now faces. Mexico joins the 40-hour “club”. With the reform, Mexico joins Ecuador, a regional pioneer in reducing the working day since 1997, and Chile, which is already in the process of transitioning from 45 to 40 hours with closure planned for 2028. The International Labor Organization (ILO) points out in its report ‘Reduction of working hours: global evolution and challenges for Latin America‘ that 48-hour work weeks remain the norm in Latin America, although some countries have moved towards shorter limits. The report highlights that reducing working hours can improve health, well-being and productivity, but clarifies that the impact depends on the economic context, the design of the reform and of complementary policies that each country adopts. Other countries with days of less than 48 hours. Beyond the aforementioned examples of Ecuador and Chile, other Latin American countries have already reduced their working hours to below 48 hours, although without reaching the 40 hours of the Mexican project. The Dominican Republic, Brazil, Venezuela, El Salvador and Honduras maintain a 44-hour day, while Colombia established it at 42 hours per week, after a gradual reduction that began in 2023 and concluded this year. In contrast, most of the economies in the region, including Mexico until now, continue with the 48-hour limit, which reflects a certain degree of immobility in the face of international recommendations and the experiences of reducing working hours that have already been carried out. in other countries. How the reduction will be applied in Mexico. Taking the example of other countries that have already followed the path of reducing working hours, in Mexico, the change will be carried out gradually, with the goal of going from 48 to 40 hours weekly without altering the scheme of a single day of rest, something it shares with the recent reforms in Chile and Colombia. The adaptation will be carried out progressively at a rate of two hours per year, so that in January 2027 the working day will become 46 hours per week; In January 2028 it will go to 44 hours and by January 2029 it will be reduced to 42 hours. In January 2030, the cycle ends and the working day will be established at a 40-hour work week. All this without applying a salary reduction. The labor challenges of Latin America. The ILO report highlights that the reduction of working hours in Latin America faces specific challenges, such as high levels of informality in contracting, limited coverage of collective bargaining and a tendency to underground economywhich conditions the scope of the reforms. Furthermore, sectors such as domestic work, moonlighting and gender gaps They require specific regulatory frameworks for their respective labor markets and not a simple copy of the models that have worked in high-income countries.

We are going through one of the shortest days in history

If you feel that days fly, it is not just a perception of yours. Our planet is turning faster than normal. This July 22 is expected to complete its rotation 1.34 milliseconds before 24 hours, turning today the second shortest day of the year and one of the shortest since we have records. Earth accelerates. Until 2020, the shortest day registered had lasted 24 hours less 1.05 milliseconds. Since then, The shortest day of each year has overcome that threshold. In 2020 and 2021, the highest deviation was −1.47 ms; in 2022, of −1.59 ms; In 2023 he rose to −1.31 ms and in 2024 he came down again, marking the current record. The shortest day ever documented occurred on July 5 of last year. He lacked 1.66 ms to complete 24 hours. 2025 silver medal. The predictions for the summer of 2025 They pointed out three key dates in which Earth’s rotation could beat its speed record: on July 9, July 22 and August 5. Finally, the shortest day of 2025 was on July 10 with a deviation of -1.36 ms. According to the latest estimates, this July 22 will be the second most short day with a duration of 24 hours -1.34 ms. On August 5 it would be third with a -1.25 ms. The world upside down. The really fascinating thing about this phenomenon is that it goes against everything we know about the rotation of our planet. For billions of years, the land has been stopping for the friction of the tides generated by the moon. Our satellite steals rotational energy to the planet, causing the days increasingly long. In fact, it is believed that during much of the history of the earth, the days lasted about 19 hours. Why it happens. We don’t know. Some researchers They attribute it to the thaw of polar capsbut the redistribution of that mass of water to Ecuador could actually be moderating the acceleration, not driving it. Earth’s acceleration has no place in any of the oceanic and atmospheric models, so the scientific community suspects mainly from the depths of the planet. One possibility is that the liquid nucleus of the earth is slowing down its movement and, to preserve the angular momentum of the planet, this internal slowdown is being compensated With a slight acceleration of the mantle and the cortexwhich is what we experience on the surface. The second intercalar … negative. Earth’s acceleration has implications for time measurement. Since 1973, atomic watches mark the coordinated universal time (UTC). Occasionally, A “second interlar” has been added To resolve our watches with the terrestrial rotation, which Historically, he slowed down. Now, we face an unprecedented scenario: the need for a second negative intercala. If the acceleration trend continues, world timing could have to subtract a second of atomic watches Around 2029. It would be the first time in history that this type’s correction is made. Image | POT In Xataka | We know since time immemorial that the days last 24 hours. Except when the wind blows

We are at the doors of the “shortest” day of our lives

If you feel that days are less, maybe it is because our planet has stepped on the accelerator. Since 2020, and for reasons that Astronomers are still investigatingthe Earth has been rotating on its axis at a speed slightly higher than usual, beating all records since we have atomic measurements. The next record could happen in a few days. The shortest documented day. According to predictions of astrophysicist Graham Jonesthere are three key dates in 2025 in which the Earth could register its fastest turn since there are records: July 9, on July 22 or August 5, 2025. In one of those three days there will be all the conditions for the Earth to approach or exceed the historical record so far, which is not very distant: on July 5, 2024. Other experts do not have it so clear and believe that the shortest day of this year could remain some milliseconds above the record last year. An anomaly of milliseconds. A solar day lasts 86,400 seconds; That is, 24 hours. However, the rotation of the earth is not perfect and has tiny variations. These fluctuations are translated into milliseconds above or below the reference figurethat we can measure thanks to the precision of atomic watches. Until 2020, the shortest day registered lacked 1.05 milliseconds for 24 hours. But since then, every year has overcome that threshold. In 2021, the shortest day was 24 hours – 1,47 ms; In 2022, it was 24 hours −1.59 ms; In 2023 it rose to 24 hours −1.31 ms and in 2024 he came down again, marking the current record. The shortest day ever documented was on July 5 of last year, which lasted 24 hours -1.66 ms. Why this summer. The dates planned for 2025 coincide with the moments in which the moon orbit places it at its furthest point from the Earth’s Ecuador. The lunar position influences the speed of rotation of our planet, although it is not the main factor of the current acceleration, which remains a mystery. The most fascinating thing about this acceleration is that it goes against the trend. For billions of years, The Moon has been braking the rotation of the Earth. About 4.5 billion years ago, one day on Earth it lasted between three and six hours. The gravitational attraction of the Moon generates the tides, and this constant friction of the oceans has been stealing angular momentum to the earth, which slows its speed. No one expected this acceleration. The models that scientists usually use take into account ocean currents and atmospheric movements, but fail to explain this sudden acceleration. The main hypothesis points to complex and still little understood processes In the core of our planet. The planet’s engine has “changed marching.” If this braking trend continued without interruption, in about 50,000 million years, the rotation of the earth would be synchronized with the orbit of the moon. The result would be a “tide blocking” where the earth would always show the same face to the moon, so that our satellite would only be visible from the middle of the planet. In any case, we will not be here. Within about 10,000 million years, the sun will become a white dwarf. Already by then, the earth will take time being uninhabitable.
