A bit of background

Traditionally, the Torah describes Rosh Hashanah as a one-day observance, but for many centuries it has been kept as a two-day holiday in most Jewish communities, both in Israel and the diaspora. Because of this, people sometimes describe it as one long, extended day of judgment and renewal, even though it spans two full calendar days.

You’ll often hear it described as running “from sunset to nightfall, two days in a row” – that’s the practical way most people experience it.
