On March 20, 2026, Romania will mark the spring equinox, when day and night become equal, signaling the beginning of the warm season.

The spring equinox will take place on March 20, 2026, marking an important moment when day and night become almost equal. On this day, the Sun crosses the celestial equator, signaling the beginning of the warm season. At the mid-latitudes of Romania, the Sun will rise exactly in the east and set in the west, and its average height at noon will correspond to its specific position. After the equinox, the duration of the day will progressively increase until the summer solstice, around June 21.

The equinox is a global phenomenon, but its interpretation varies depending on the hemisphere; in the southern hemisphere, it marks the beginning of autumn. Additionally, equinoxes do not have fixed dates due to the precession of the Earth's axis, but the Gregorian calendar maintains the spring equinox almost consistently on March 20 or 21. Furthermore, Romania will switch to daylight saving time on the night of March 28-29, 2026, when clocks will be set forward by one hour, aligning the official schedule with the standard time zone.
