A time bank is a community-based system where people exchange services using time as currency. Instead of money, participants earn credits by providing help to others, which they can later use to receive help in return. For example, if someone spends an hour tutoring a child, they earn one time credit, which they can use to receive an hour of gardening help from another member. Time banks promote social connections and encourage community engagement. They can help individuals develop new skills, build relationships, and support one another. This system is often organized by local groups or organizations, fostering a sense of cooperation and mutual aid among participants.
