How this was calculated

Starting from the present moment — Thursday, May 21, 2026 — we add 11 months backward through the calendar. The result is Saturday, June 21, 2025.

Verification (ISO 8601): 2025-06-21. This is a Saturday, day 172 of 2025, in ISO week 25.

Note: month and year arithmetic uses calendar-aware rules, not 30/365-day fixed lengths. For example, adding one month to January 31 yields February 28 (or 29 in a leap year), not March 3 — the day-of-month is clamped to the target month's last day. Adding one year to February 29 in a leap year yields February 28 of the following year, preserving the month and clamping the day.
