Of all the days in a year, April Fools Day is the absolute worst day to send a press release to the wires. This is noted in a Shift Communications report detailing the worst times to release a press release. Journalists and media outlets are unlikely to take your release very seriously if it is sent out on this day notorious for jokes and pranks. This greatly minimizes your chances of getting picked up in an outlet or of having a reporter inquire for further information.

As the week winds down, newswires see less and less activity. Fridays are slow, and not many releases at all are distributed on the weekends. Mondays and Tuesdays are the busiest days of the week for press release distribution, with the early hours of 8 and 9 AM seeing the highest concentration of releases. Firms should try to get as many eyes as possible on their releases by going further than just sending the release and hoping something comes of it.
