I am currently using InMotion Hosting to host my websites and wanted to add a social media site to the group of sites. When I try to install Open Source Social Network via Softaculous though, it is asking for a birthdate for the admin account. No matter how I try to enter the birthdate though, it keeps telling me I have the wrong numbers listed for the date and the year or the month and the year, or all three. I can't seem to find the right combination of numbers to get it to accept. For example, I have done (not using my real birthday here): 6/1/1984 (M/D/YYYY), 1/6/1984 (D/M/YYYY), 1984/1/6 (YYYY/D/M), 1984/6/1 (YYYY/M/D), 6/1984/1 (M/YYYY/D), and 1/1984/6 (D/YYYY/M).

Can anyone tell me what the correct date format for birthdays are?

Thanks!
