Anomaly scan date confusion

My NT scan redated my EDD to 26 December 2026.

NT was done in 18th June 2026- gestational age after redating on that day was - 12weeks 5 days.

On my card, the anomaly scan is written as August 18 to September 7. Could you please confirm if that’s correct? I thought it is usually done around 20 weeks and before 23 weeks.
