Sausio

Sausio is the genitive form of the Lithuanian noun sausis, referring to January, the first month of the Gregorian calendar as used in Lithuania. The form sausio appears in phrases that reference time within January, for example sausio mėnuo meaning the month of January, and sausio 5 d. meaning January 5. In everyday and formal writing, the month name is often used in this genitive form when dates are specified.

In Lithuanian, month names are declined, and when indicating a specific date the day is written in ordinal form and the month in genitive. Common constructions include sausio 5-ąją for “the 5th of January” and sausio 1-ąją for “the 1st of January.” The year is typically placed after the date with the abbreviation m., as in 2025 m. sausio 5 d. This pattern is used across Lithuanian dates and is comparable to how other months are expressed in genitive form.

Sausio falls in the winter season in Lithuania and the Northern Hemisphere, commonly associated with cold weather and shorter daylight hours. It marks the beginning of the calendar year and is referenced frequently in news, schedules, and cultural contexts when specifying events or timelines that occur in January. The genitive sausio is the standard form for such references in contemporary Lithuanian usage.
