Adverbs with –s-
Many nouns with time-related meanings can be transformed into adverbs by adding the letter –s

montags, dienstags, etc
sommers, winters but not Herbst or Frühling
morgens, mittags, abends
zeitlebens (all one’s life)
anfangs

Many of these adverbs signify a repeated occurrence of the time point/frame indicated: Montags gehe ich zur Deutschklasse. (I go to my German class on Mondays.)

Adverbs with two timeframes/points in time
einst/ once, at one time: used to describe a timeframe/point in the future as well as the past. For example,

Einst wollte er heiraten, aber jetzt nicht mehr. (At one time he wanted to get married, but not any more.)
Einst wird der Tag kommen, wo ich Großmutter sein werde. (The day will come where I'll be a grandmother.)

gerade: used to describe a timeframe/point in time in the present as well as the past that just occurred. For example,

Mein Vater ist gerade bei der Arbeit. (My father is at work at present.)
Sie ist gerade zur Kirche gegangen. (She just went to church.)
