21 months from today follows the calendar convention used by banks, leases, and subscriptions: keep the same day of the month and move forward 21 months, landing on Friday, April 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 640 days, not 630. For exact day counts, use days from today.
