This is what the Gregorian calendar does,which were needed corrections, and thus is not offensive to God.
The motivation for devising the calendar was to reset the proper timing for Easter, and then the calendar 'ended up' named after a pope name Gregory, which makes this quite a fascinating trail:
γρηγορεύω grēgoreúō, gray-gor-yoo'-o; from G1453; to keep awake, i.e. watch (literally or figuratively):—be vigilant, wake, (be) watch(-ful).
From:
ἐγείρω egeírō, eg-i'-ro; probably akin to the base of G58 (through the idea of collecting one's faculties); to waken (transitively or intransitively), i.e. rouse (literally, from sleep, from sitting or lying, from disease, from death; or figuratively, from obscurity, inactivity, ruins, nonexistence):—awake, lift (up), raise (again, up), rear up, (a-)rise (again, up), stand, take up.
As you can check at the above link, egeírō is used for the Resurrection, the timing of which was the point of correcting the Julian calendar.
See, what's in a name? You just never know what will appear on closer inspection. And here we are, talk about timing. :)
