How 18 months ago is counted
Today is day 0. Going back 18 months gives the date in the box above, worked out on your device for your time zone, so it's right wherever you are. Months are counted on the calendar: the same day of the month, moved to the last day when a month is shorter (one month after January 31 is February 28, or 29 in a leap year).
For example, from Sunday, October 11, 2026, 18 months earlier is Friday, April 11, 2025.
