+
+There's a common saying about not deploying changes on a Friday to prevent outages or issues before the weekend.
+
+I've also seen this where people won't deploy after a particular time of the day as it's too close to the evening.
+
+## When did you last deploy?
+
+The longer it's been since the last deployment, the risker each deployment is.
+
+If there are weeks or months of changes, it will be risky regardless of which day it is.
+
+If your last deployment was an afternoon, deploying a small change the following morning will be low risk, even on a Thursday and Friday.
+
+## Conclusion
+
+If you're nervous about deploying on a Friday, I think you need to aim for smaller and more frequent deployments to minimise the risk.
+
+The issue isn't when you're deploying. You likely need to do so more often.
+
+If there is an issue after a large release, it will take more time to debug or roll back compared to a small release which is easier to find and fix the problem or revert that single change.
