“Have you not heard Paul saying, “You keep days and months and seasons and years; I fear lest I have laboured in vain for you”? Otherwise it is of the most extreme folly that from one day, if it be fortunate, to expect this from the whole year; but it is not of folly alone, rather this is the judgment of diabolical activity, not to entrust the things of our life to our own haste and eagerness, but to cycles of the days. The whole year will be fortunate for you, not if you are drunk on the new-moon, but if both on the new-moon, and each day, you do those things approved by God. For days come wicked and good, not from their own nature; for a day differs nothing from another day, but from our zeal and sluggishness. If you perform righteousness, then the day becomes good to you; if you perform sin, then it will be evil and full of retribution. If you contemplate these things, and are so disposed, you will consider the whole year favourable, performing prayers and charity every day; but if you are careless of virtue for yourself, and you entrust the contentment of your soul to beginnings of months and numbers of days, you will be desolate of everything good unto yourself.”

Saint John Chrysostom, On the Calends of January)
