Usage notes
Sonntagsspaziergang usually means a walk on a Sunday. In Germany/Austria/Switzerland, most people have the fewest obligations on a Sunday (no work, no school). If the speaker is not talking about any particular Sunday, it could mean a relaxing walk on any day both the speaker and recipient are the least busy. This includes Sunday, but could mean upcoming statutory holidays and possibly Saturdays, too. Once a date for a relaxing walk on any day has been picked, it is usually not referred to as Sonntagsspaziergang anymore (except if it is indeed on a Sunday).
