How the months are counted
We step forward whole calendar months from today, keeping the day of the month, and stop at the last step that does not pass Summer. The days from there are the leftover days. Today is November 10, 2026. 7 months from November 10, 2026 is June 10, 2027. From there it is 11 days to June 21, 2027.
When the landing month is too short for the day, we use its last day: January 31 plus one month is February 28, or February 29 in a leap year. So January 31 to March 1 is 1 month and 1 day. Each step is measured from today, so January 31 plus two months is March 31. Months have 28 to 31 days, so a month here is a calendar count, not a fixed number of days.
The weeks figure is simply the total days divided by 7, with the remainder as days.
