Giving sadaqah to start your day is baseless in Islam and it is an innovation.

The money which you had collected will be accepted by Allah as charity

I’ve heard it’s good to start your day by giving sadaqah, I’m a girl and cannot go outside and start my day by doing so. Instead, I’ve a money box in which every morning I put some money and at the end of the month, I give that money to some needy. Will it be accepted as sadaqah for each day, if I just keep it in money box and give it away at the end of the month.
