Loveday is a Cornish-English name derived from a medieval institution called the "love-day" — a day appointed for resolving disputes by mediation rather than legal action.
Loveday is rare but rising in Cornwall and the UK.
Loveday does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Loveday reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
