18 months from today follows the calendar convention used by banks, leases, and subscriptions: keep the same day of the month and move forward 18 months, landing on Friday, January 28, 2028. 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 549 days, not 540. For exact day counts, use days from today.
