The date convention
End date = start date plus the term in calendar months, minus one day. A start on the 31st clamps to the last day of shorter months, so 31 January plus one month is 28 or 29 February. Some brands count from installation or invoice date, or use different rules; check your card.
Questions
Does this confirm my item is under warranty?
No. It is date arithmetic on the terms you enter. Coverage depends on the brand’s conditions and their assessment.
