Part of a day
For this calculation, the Act says that part of a day is not a day.1

Worked example

Two trips leave one day of room

  1. Apply on 1 November 2026 with the earlier 4 years already met. A trip from 10 January to 20 February 2026 has 40 days outside in the continuous year.1How we count: Counting dates strictly between departure and return gives 21 days from 11 to 31 January plus 19 from 1 to 19 February: 40.
  2. A second trip from 1 to 31 July 2026 adds 29 days outside, from 2 through 30 July.1How we count: July has 31 days; excluding 1 and 31 July leaves 29.
  3. The continuous year from 2 November 2025 through 1 November 2026 contains 40 + 29 = 69 days outside, one below the usual 70-day allowance.1How we count: 40 + 29 = 69. 70 - 69 = 1.

The rule it rests on: You need one year of continuous residence immediately before applying, plus four years in the preceding eight years. Up to 70 days outside Ireland may be allowed in the continuous year.1 The continuous year ends on your application date. The four earlier years of reckonable residence come from the 8 years before that year.1
