The lifespan of a developer depends on the nature of the developer and varies widely. Rodinal and HC-110 concentrates last for years. Most developers are good for about 6 months if properly stored. Best to make up an amount that can be used in a reasonable length of time depending on your own usage.
Noted, Gerald. Thanks.

You meant 20 Farenheit?
For a tropical country, 20 degree celcius is definitely cold Normal temperature is 32-33 degree celcius.
Does store the solutions in a hot temperature can cause the solution to expire faster?

The refrigerator temperature in Jakarta is as the same as the room temperature in europe I guess
