Depends on your ops manual.
Its more to do with currency than anything else.
Some have 28 days and others the full 90. And some nothing at all.
So it depends on the local NAA what they want.
Most western airlines have a 28 day currency of 3 TO and landings. Which can be done minus pax with a LTC or above or in the sim.
I know people that haven't been near an aircraft never mind the type for 5 months then start training. By all accounts it wasn't pleasant.
