My Time Deposit pays 1.8% annual interest and I accrue pro-rata 0.493% interest per day (as I can renew after 7 months, I will recieve 0.493% x 365 days = 1.8% after 12 months). This concept is no different to a 24 month time deposit paying 1.8% interest, you will accrue 0.493% per day for 2 years.
On my actual 805k deposit, I receive 1231 baht per month interest on 31 day months and 1191 baht on 30 day months. This is paid into my regular savings account on the 20th of each month. This means my 805k time deposit balance never changes.
