I've been thinking about creating a budgeting app that finally does away with months. I hate setting a budget for a month and would instead love to do a 30 rolling window.
- konschubert 4y agoPlease do it and tell me about it.
- nerdponx 4y agoThis is a great idea. It would be really useful if you could just put in income and expenses with dates attached, and have the app compute things in windows of various sizes, as well as traditional calendar-based periods.
- mbork_pl 4y agoYou can use ledger (https://ledger-cli.org/ https://ledger-cli.org/) for that: ledger bal <filters> -f <journal file> -b "28 days ago"

- doh 4y agoThis was the logic Brex started with when they first introduced their corporate cards. The rolling window started wrecking havoc very quickly. For instance, we gave all employees $300/month budget for parking garage. However, on some months they would charge the card on 5th of the month, on another at 11th, etc. It was literally unusable and we left for another provider (later Brex also went back to calendar days). While this might not be an issue for your application per se, the real world operates on calendar days. You will quickly run into situations where 30 day rolling window not only doesn’t work but is explicitly causing problems. My 2 cents.
