Middlesex Baptism record - confusion over year

Cyrilthebad

Grateful for thoughts on which year date I should use for the attached baptism records. Page 164 (left hand page) has the date as 1821 Jun 10 the next page 165 has the date 1820 Jun 10 - I can of course index it exactly as it is but somehow it feels wrong - the next pages along in the batch refer to pages 168 & 169 (no sign of pages 166/167) but page 168 clearly starts 1821 Jun 10.

I would type just what you see. The researchers who are led to this image are the ones who get to interpret the data.
