The number of days in 2 months depends on which months you are referring to, because different months have different lengths:

• January, March, May, July, August, October, December = 31 days each
• April, June, September, November = 30 days each
• February = 28 days (29 in a leap year)

Examples:

• If the 2 months are January and February (non-leap year):
  31 + 28 = 59 days

• If the 2 months are March and April:
  31 + 30 = 61 days

• If the 2 months are July and August:
  31 + 31 = 62 days

Average:

On average, a month is about 30.44 days, so:
2 months ≈ 2 × 30.44 = 60.88 days (approximately 61 days) If you want a precise answer, please specify which months you mean!
