Determining the Day of the Week for Kostya's Birthday

To determine the day of the week on which Kostya celebrated his birthday, we need to consider the following information:

- Masha's birthday was on August 18th, which fell on a Thursday this year. - Kostya is older than Masha by 2 years and 57 days.

To find the day of the week for Kostya's birthday, we can calculate the date by subtracting 2 years and 57 days from Masha's birthday. Let's break it down step by step:

1. Subtract 2 years from August 18th: August 18, 2023 - 2 years = August 18, 2021. 2. Subtract 57 days from August 18, 2021: August 18, 2021 - 57 days = June 22, 2021.

Therefore, Kostya's birthday was on June 22, 2021. To determine the day of the week for this date, we can use a calendar or an online tool. According to the calendar, June 22, 2021, fell on a Tuesday.

So, Kostya celebrated his birthday on a Tuesday in 2021.
