Claim: Department for Education research shows missing school for even a day can impact pupil attainment.
Fact-check: Mixed evidence on the link between term time holidays and attainment  - Full Fact
Verdict: this research finds as pupil absence rates increase, they do worse in tests at ages 10/11 and 15/16. missing a single day doesn't always show this for some pupils though, if the absence is an authorised holiday. either way, the findings can't prove that missing school is the cause of worse performance, or at least that if it is a cause, it's the main one. the evidence is more mixed looking specifically at holidays as a reason for absence.
