How far do you think I would have to tt in order for all my grass to grow back? Or all the grass possible...
Generally, a month long leap forward is enough to regrow all the worn grass (except for any permanent dirt patches). Just be careful to enact the Beautiful Town ordinance and make sure nobody is moving before you make the jump! The safest way to go forward is to wait until somebody is thinking of moving, turn them down, and then immediately save and time travel forward. The logic is that if you turn down a mover on that day, you can be absolutely sure that nobody else wants to move and you can time travel forward as far as you like without losing anyone.
