+## Timing
+
+General rules:
+
+* Months are bounded by the first Wed. Thus, development in May 2018 actually lasts from 2-May-18 to 6-Jun-18.
+* Release dates are usually construed in US/Pacific time. Thus, a release on 7-Apr-21 in US/Pacific time may
+  be 8-Apr-21 in AU/Eastern time.
+* On a designated *Release Date*, all three main branches (development, RC, stable) will usually be updated on the same day.
+
+Those are not absolute rules -- exceptions may arise a couple times a year. For example:
+
+* If the first Wed of a month coincides with major holiday (e.g. New Years Day), then it could be moved.
+* If there is an important patch near completion, the new RC could be delayed an extra day.
+
 ## Philosophy
 
 Reviewing and testing are natural, important, on-going parts of software-development, but they generally cannot be done by the original developer. All developers have a shared interest in having their changes reviewed by a neutral and competent party. The goal of the release-cycle is to match-up developers who are willing to check each other's work, and to bring in feedback from non-developers to improve quality assurance.
