How is a lease term defined when tied to a specific religious festival ('Eid')?

Primary text

If one leases property until the 'Eid', it refers to the immediately subsequent 'Eid', and the lease attaches to its very first moment, as that moment marks the end point specified for the lease duration. Similarly, if the term is tied to a month whose name is shared by two months (like Jumada or Rabi'), the stipulator must specify the first or second one, and the year. If tied to a singular month (like Rajab or Sha'ban), the year must be specified. If tied to a specific day, the week must be specified according to one opinion.
