This is a simple public listing of submission deadlines for academic or research-oriented finance conferences.
The list is in no way comprehensive. The American Finance Association also maintains a calendar.
If you would like a conference added to the list, please open an issue. I have created a template to make it straightforward. Alternatively, you can add your conference to the file data/financeconfdeadlines.csv and submit a pull request.
This list comes with no guarantees.
Thanks to Thibaut Lienart for creating Franklin.jl.
