This is a 7 day Money jar.  7 Day jars are to set intentions and allow the candle to burn for 7 days straight to help with manifestation.  While you can't always allow a candle to burn continuously like this, you can light it and allow it to burn in your home for 7 consecutive days, snuffing it out when you leave.  Never blow out a candle as it can blow out your intentions.  Reset your intentions every day right before you light it.
