  "method": "Find the first July 26 on or after the start date, then count the days from the start date to it.",
  "assumptions": [
    "July 26 comes every year, so the count is never more than 365 days.",
    "The start date itself is not counted: from the day before July 26, the count is 1; on July 26 itself, it is 0.",
    "Start dates from January 1, 1900 to December 31, 2400 work for the count to July 26, the range the date field accepts.",
    "Today is the date on your own device, so the count to July 26 changes at midnight where you are. Dates are whole calendar days, so a daylight-saving change never adds or loses a day."
