Tanggal dimulainya Blancan masih belum sepenuhnya didirikan. Terdapat persetujuan umum bahwa tanggalnya sekitar 4.9<ref>Lindsay ''et al.'' (2002)</ref> dan 4.3 juta tahun yang lalu ("mya").<ref>Cassiliano (1999)</ref> Database GeoWhen yang sering dikutip menempatkannya pada 4.75 mya.<ref name="GeoWhen"/>
Lebih kuat lagi ketidakcocokan mengenai akhir zaman Blancan. Sejumlah [[Stratigraphy|stratigrapher]] mengusulkan tarikh 1,808 mya yang lebih bersesuaian dengan akhir zaman [[Pliocene]] dan permulaan [[Pleistosen]] (1,808 mya). Ini juga selaras dengan tarikh kepunahah kumpulan fauna ''[[Borophagus]]'', ''[[Hypolagus]]'', ''[[Paenemarmota]]'', ''[[Plesippus]]'', ''[[Nannippus]]'', and ''[[Rhynchotherium]]'' antara 2,2 dan 1,8 mya.<ref name
