The word is made up of 'bis' (until/to) and the old word 'weilen' (to linger, to stay for a while). This origin helps you remember the meaning 'from time to time' or 'sometimes'.

'immer' and 'bisweilen' both describe how often something happens, but they are opposites. 'immer' means without exception or at all times. 'bisweilen' means only sometimes or from time to time. 'bisweilen' sounds somewhat more elevated than 'manchmal' and is more suitable for written or slightly more formal language. The simple difference is: 'immer' happens every time, while 'bisweilen' happens only occasionally.
bisweilen
Im Sommer arbeiten wir bisweilen auch im Garten.
In the summer, we occasionally also work in the garden.
