17 months from today follows the calendar convention used by banks, leases, and subscriptions: keep the same day of the month and move forward 17 months, landing on Tuesday, December 28, 2027. When the starting day doesn't exist in the target month (the 31st of a 30-day month, or February), the date clamps to the month's last day. That makes month arithmetic different from day counting — this particular span covers 518 days, not 510. For exact day counts, use days from today.
