Can a retaining wall be built in a single day?

For a genuinely small, straightforward wall, possibly — but most residential retaining walls take several days to a week or more, factoring in excavation, post installation, drainage, and the wall construction itself.

Taller or longer walls, or those needing engineering certification and inspection, genuinely take longer given the additional design and compliance steps involved beyond just physical construction time.

Your contractor can give you a realistic timeframe once they’ve assessed your specific wall’s height, length and site conditions, rather than relying on a generic single-day expectation.
