The Lifespan Duration Function setting determines how long a guest has to redeem their anniversary reward, relative to the date they are gifted.
- "Month of Reference Date" and "Week of Reference Date" means the guest must redeem their gift in the same month or week of their anniversary date, respectively;
- "Reference Date Only" means it must be redeemed on the exact anniversary date;
- For "Fixed" the Reward will be available until the date you select; and
- For "N Days from rewarding" you can choose a number of days before and after the anniversary date when the guest may redeem their gift.
