Janus is the name of the month January, and what is its Roman origin?

The name of this period derives directly from Janus, the Roman god of gates, transitions, and beginnings, who had two faces looking simultaneously towards the past and the future.

Historians indicate that Numa Pompilius, the second king of Rome, introduced the month around 713 BC, aiming to adjust the lunar calendar to the seasonal cycles of ancient Italian agriculture.

Previously, the Roman calendar had only ten months, starting in March, which left a gap during the winter, later filled by January and also by the month of February.

The choice of Janus as a patron reflects the symbolic need for self-reflection, allowing people to analyze past mistakes while planning new journeys under the protection of this two-faced deity.

When did the calendar change to make January the first month?

Originally, the new year began in March, coinciding with the spring equinox in the northern hemisphere, a time when military campaigns and agricultural planting were vigorously resumed.

The definitive consolidation came with Julius Caesar's reform in 46 BC, establishing the Julian Calendar, which permanently fixed January 1st as the starting point of each cycle.

Even after the fall of Rome, many European nations used different dates until Pope Gregory XIII, in 1582, standardized the system that we widely use in almost the entire world.

What are the main astronomical characteristics of this period?

During the month of January, planet Earth reaches perihelion, the point in its elliptical orbit where it is closest to the Sun, approximately 147 million kilometers away on average.

Although many associate proximity to the sun with heat, the seasons depend on the tilt of the Earth's axis, resulting in harsh winters in the Northern Hemisphere and intense summers throughout Brazil.

This month also features the Quadrantid meteor shower, one of the most intense celestial events of the year, offering a magnificent visual spectacle for observers in regions with low light pollution.

Astronomers point out that the visibility of constellations like Orion reaches its peak, facilitating amateur and professional study of the stars in both hemispheres due to the clear summer nights.

Currently, the concept has evolved into a self-help and productivity approach, where millions of people use digital tools and calendars to organize their health, career, and ongoing personal learning goals.

Why is January considered Mental Health Month?

Recently, the "White January" movement has gained momentum in Brazil, using the beginning of the year as a metaphor for a "blank page" to encourage care for emotional and psychological well-being.

The campaign argues that, just as we plan our finances and travels, we should prioritize mental well-being, preventing illnesses such as depression and anxiety through open dialogue and appropriate professional support.

Experts say that the pressure to make New Year's resolutions can lead to stress, making it essential to approach this month with self-compassion and realistic goals that don't compromise an individual's internal health.

The choice of white as the color symbolizes the possibility of writing a new story, reinforcing the importance of public policies and social debates about quality of life at all ages.
