Olympiad end cycle, and start of new one

My olympiad doesnt end, i dont really know why, but i have a strong guess its due to this:

`id`  `current_cycle`  `period`  `olympiad_end`  `validation_end`  `next_weekly_change`

0                1                  0        128333880085    1282716000        1283136507859

Could anyone explain me how to set this up
