Roman calendar date
Ovid’s calendar places the spring equinox, when day and night are equal, on 26 March.
Background
Romans divided daylight into twelve hours, whatever the season, so a summer hour was long and a winter hour short. The spring equinox, when daylight and darkness were equal and hours were the same length day and night, was a natural marker of the farming and sailing year.
Julius Caesar's calendar reform of 46 BC had put the year back in step with the sun, and Ovid, writing under Augustus, records the equinox on 26 March: "when the Morning Star has three times heralded the dawn" after the Tubilustrium, "you'll find the daylight hours are equal to those of night." Astronomers today would place the equinox of Ovid's time a few days earlier, around 23 March modern calculation; Roman almanacs used traditional dates rather than precise observation.
The same day had another meaning by late antiquity. The Calendar of 354 marks 26 March as REQVETIO, "rest", a quiet day in the Great Mother's festival between the joy of the Hilaria and the washing of her statue on the 27th. For farmers, the equinox meant longer working days ahead; for the city, a pause between celebrations.

Fields & crops
Columella calls March the best time for pruning vines and the first digging of vineyards; spring crops like millet were readied per Columella 11.2.
Courts & law
Legal and public business resumed in full after winter. At the Liberalia (17 Mar.) many boys put on the plain toga of manhood and were enrolled as adult citizens, with a family procession to the Forum per Ovid, Fasti 3.771–88.
Senate & politics
From c. 222 to 153 BC the consuls entered office on the Ides of March; Livy records it for 217 BC, and the starting year is a modern reconstruction per Livy 22.1.4. From 153 BC they took office on the Kalends of January per Livy, Per. 47. Caesar was killed at a Senate meeting on the Ides of March 44 BC per Suetonius, Velleius.
Military
The month of Mars opened the campaign season. The Salii carried the sacred shields, and the Tubilustrium (23 Mar.) purified the war trumpets per Varro and Ovid.
Festivals & religion
Matronalia (1 Mar.), Liberalia (17 Mar.), when boys often took the man's toga, and the Quinquatrus of Minerva (19–23 Mar.), a holiday for craftsmen, teachers and doctors per Ovid, Fasti 3.
Daily life
March, once the first month of the year, reopened the seasons of war and sailing. The Salii, Mars' leaping priests, danced through the city. On the Kalends (Matronalia), married women received gifts and in turn served a meal to the household's enslaved people per Macrobius 1.12.7; Ovid, Fasti 3. Columella treats March as prime time for pruning vines and digging per Columella 11.2.
For soldiers, the campaign season began; for traders, sea routes reopened and grain ships from Egypt and Africa could sail again, easing city food supplies.
