Scottish term and quarter days are the four divisions of the legal year, historically used as the days when contracts and leases would begin and end, servants would be hired or dismissed, and rent, interest on loans, and ministers' stipends would become due. The Term Days are Whitsunday and Martinmas, and together with Candlemas and Lammas they constitute the Quarter Days. Although they originally occurred on holy days, corresponding roughly to the old Celtic quarter days, they were fixed by the Term and Quarter Days (Scotland) Act 1990 as falling on the 28th day every three months, thus:

• Candlemas (2 February)
• Whitsunday (15 May)
• Lammas (01 August)
• Martinmas (11 November)
