哪种方法最常见？Which method is most common?
没有统一规定，以租约约定为准。三种方法都很常见：“当月实际天数”= 月租 ÷ 当月天数 × 居住天数；“全年 365 天”= 月租 × 12 ÷ 365 × 居住天数（闰年也按 365 天）；“每月 30 天”= 月租 ÷ 30 × 计费天数。There is no single rule — your lease decides. All three methods are common: actual days = rent ÷ days in that month × days occupied; 365-day year = rent × 12 ÷ 365 × days occupied (365 even in leap years); 30-day month = rent ÷ 30 × days charged.
入住当天算不算？Is the move-in day counted?
算。入住时从入住当天计到月底；退租时从 1 日计到退租当天。Yes. Move-in counts from the move-in day through month end; move-out counts from the 1st through the move-out day.
