title: Google sheets. Lock range
body: <p>I have 2 lists with ranges C2:F21, which should be available to fill for all users in a certain period. </p>
  
  <p>Range  C2:F21  in the list A shouldn't be locked from 01.01.2020 to 05.01.2020, but in another time it should be locked for all users except me. </p>
  
  <p>In the list B range C2:F21 shouldn't be locked only from 01.02.2020 to 05.02.2020.</p>
  
  <p>I will be very grateful for any answer</p>
