Asking to not present in a conference on Saturday I am about to submit a paper to a conference. I just found out that the conference falls in Wednesday, Thursday, Friday and Saturday. Since I am an observant Jew, I don't want to present on Saturday. What are my options?


I thought to submit the paper, and if it is accepted, explicitly ask the organizers to schedule me to another day. Is this possible/acceptable?
Another option is to submit the paper, and if it is accepted and scheduled on Saturday (and the organizers don't agree to change this), then withdraw the paper. This is of course less preferable as it, probably, creates bad reputation if I don't present an accepted paper (I am also not sure if it will be published: Presented a paper in a conference, but my paper did not get published in proceeding )
The third option is not to submit at all, in order to prevent the option that I have to withdraw an accepted paper.
If your paper is accepted is it perfectly appropriate to ask them to observe your religious guidelines. A lot of people will give special date restrictions when presenting in a conference for lesser things like they need to fly home by a certain date, their funding doesn't cover hotels for the length of the conference, or they just don't have a desire to stay the whole time. 

Good luck with presentations!
